What was the worst thing ever to happen to you on a date?

I had one date with someone I met through a mutual friend. I picked her up and we went out to dinner and it felt like things were going OK, but I got the feeling that she was one of these people who loves talking about herself but is a terrible listener At the restaurant the subject of pets came up, she said something like "I fucking hate cats How could anyone like cats". Being a huge cat lover and having 3 cats at the time I rather took offense to this I wouldn't wait for the date to be over. :-) The kicker is, when we said our goodbyes as I dropped her off, she asked if she could see me again. lol I had said virtually nothing as I was driving her home and was just listening to her yammer on about this and that.
