I was looking up images of symbols for various words as I sometimes do and I googled (images) 'symbol for hospitality' and a bunch of pineapples popped up. I found the following excerpt on this website:

A hostesses's ability to have a pineapple for an important dining event said as much about her rank as it did about her resourcefulness, given that the street trade in available fresh pineapples could be as brisk as it was bitchy. So sought after were the prickly fruits that colonial confectioners sometimes rented them to households by the day. Later, the same fruit was sold to other, more affluent clients who actually ate it. As you might imagine, hostesses would have gone to great lengths to conceal the fact that the pineapple that was the visual apogee of their table display and a central topic of their guests' conversation was only rented.

Further:

In larger, well-to-do homes, the dining room doors were kept closed to heighten visitors' suspense about the table being readied on the other side. At the appointed moment, and with the maximum amount of pomp and drama, the doors were flung open to reveal the evening's main event. Visitors confronted with pineapple-topped food displays felt particularly honored by a hostess who obviously spared no expense to ensure her guests' dining pleasure In this manner, the fruit which was the visual keystone of the feast naturally came to symbolize the high spirits of the social events themselves; the image of the pineapple coming to express the sense of welcome, good cheer, human warmth and family affection inherent to such gracious home gatherings.

Would anyone be able to further elaborate?

Thanks in advance, love the sub.
