When did drinking at the office and in business meetings stop being a thing? In a lot of movies and series, for example Mad Men, if someone came to your office for a meeting you offered them a drink. Was that really something that people did or is it just in the movies?

From a previous answer to a similar question here by /u/jaxsson98, the amount of client entertainment that could be claimed back against tax was reduced in the US, making it more expensive for companies to provide drinks.
As time went on, it would have become less expected of a company to entertain with alcohol, at least formally.
