Wine-ing About The Size Of The Shirt

(I’m at the pub with some friends, and I go to the bar to order a round of drinks. While the girl working behind the bar is sorting out the drinks, the following conversation takes place:)

Girl: “I really like your top!”

Me: “Oh, thanks! It’s from [Shop] — actually, it’s in the sale at the moment. You should have a look on their website!”

Girl: “Ooh, really? Thanks! I will!”

(She then goes over to the wine fridges at the other end of the bar, turns around, and calls out to me:)

Girl: “Is that a large?”

Me: “Um…?”

Girl: “OH! THE WINE! Is the WINE a large?!”
