Hi there!

This is a great question for a few reasons, and a bit more in depth than you realize :) Let me see if I can help! You've inadvertently asked a pretty big question, so this is going to take multiple posts for me to answer.

Im assuming people were partying and drinking

So, the first thing we need to remember is that Titanic wasn't a cruise ship, she was an ocean liner. When we think of cruise ships today, we think of 24 hour gluttony and leisure, but this was not the case in 1912. Titanic sailed at a time when the post industrial revolution had introduced a true world economy, and which required frequent travel between Europe and North America. It would be simplest to compare to North Atlantic shipping trade to modern airplanes, but it doesn't quite fit. Yes, they transported passengers, cargo, and mail but due to the length of a crossing, shipping companies had to lure customers with amenities that made the crossing enjoyable. White Star Line and Cunard Line built their first decade liners in direct response to the Germans, who suddenly entered the race with not only size and speed...but luxury. The British had to compete quickly due to how much shipping effected the overall economy, so much so they even funded Cunard in their buildings of Mauritania and Lusitania, which drew customers with promises of speed. You could cross the Atlantic in 5-6 days on Cunard, with some comfortable accommodations to boot.

White Star had to respond, and since they did not have the governmental support of Cunard, they fitted their liners with older turbine engines. To compensate for the extra day it would take their proposed Olympic Class liners in the bustling, booming, rushing, hurrying early 20th century global economy, they promised unparalleled luxury- and that is what Titanic delivered.

Side note not real pertinent but interesting: Titanic's fame and prestige was going to be short lived. The Germans were due to launch Imperator later that year which would be bigger, faster, and more luxurious than the Olympic Class- taking the plainer, less inspired, parts critiqued about Titanic and developing them to more impressive design.

It's important to know all this because it sets up the world in which Titanic set out. Sailings were absolutely social events, of course, but they were not parties or vacations that we have now. Sailings were business and necessary travel, and customers chose their ship based on what they prioritized. If they needed to get across the Atlantic fast, they'd chose a Cunarder. If they were able to take a more relaxing trip, say sailing to a vacation, they might take White Star and revel in its comfort and pampering. While Titanic's pantry was generous with both food and liquor, there was no partying, Edwardian raves or anything of the like. It simply wasn't done. There may have been dances. We have a small handful of references to dancing on Titanic, and we know they were held on Olympic, but over a century of testimony hasn't turned up anything really. We would think if there were an organized dance, someone would have mentioned it at some point, but they don't. A few vague references but no anecdotes or stories or testimony. A bit weird actually.

But not to say that White Star didn't offer recreation, of course they did! In First Class, there was gentleman's smoking room, a ladies reading and writing room, the lounge and reception area, a library, a squash court, a barber, a gym, a swimming pool, and a sauna. Meals were social events, but Titanic also offered a la carte restaurants and cafes, including what was colloquially known as "the Ritz". The Ritz wasn't a real Ritz, they had a contract exclusively with the Germans, but White Star simply took the concept and staffed it with a private team of Italian managers and waiters who sailed as passengers, not crew.

As far as I know, Olympic and Titanic were the first two liners to offer dining options outside of the main dining room, and passengers could eat whenever they liked as the restaurant stayed open from 8am until 11pm. Passengers who chose to dine exclusively in the Ritz were given a refund on their ticket.

Second class offered much the same- a general room, library and smoking room while third offered a smoking room, reading and writing room and a general room- which included a piano. We do know third class would have involved much music, as we have reports of pipes being played on deck and the night activities being so loud they were disrupting the postal workers. Since their saloon was well forward, and they most likely bunked on F-Deck (well below the third class general room), we assume they mean at work- as the third class post office was located just outside the general room. It is possible, if they were staying on F Deck, that they were referring to the noise from the third class dining room which shared their level.

I say all this because, in answer to your question, all of these spaces were supplied by their own bar, as well as various saloons for different crew departments.

And these saloons were well stocked. 15,000 bottles of beer, 1000 bottles of wine, 26 barrels of wine and about 800 bottles of liquor including over 100 cases of brandy, cognac, vermouth etc. Titanic was well and truly loaded in all definitions of the word :)

SO, now with all THAT out of the way, let's get to your question more directly :)
