We were on one of the islands, in a pretty busy, quite large restaurant. I think it was meant to be Italian food. Anyway, I just wanted a plate of spaghetti. I'm one of those weird people who likes lots of tomato sauce - so I ask for extra when I placed my order. The server assures me that it comes with plenty of sauce.
Our orders arrive, and, as I had worried, mine is woefully dry. When the waiter comes round to ask how everything is, I ask if I could have a bit more. Politely, I swear! I have an intense fear of confrontation. He leaves...and then comes back a few minutes later, plunks a bottle of ketchup on the table in front of me, and walks off without a word.
I'd say it's hilarious in retrospect, but...it was pretty funny at the time, too.
