I've only been hit on once in my entire life. It was outside at the soda machines at Wal-Mart.
Anyway, so I was about to get a soda when a guy walks up to me and says "Do you have a boyfriend? Do you want one?" And I said no, then turned back to the soda machine and put my money in. I didn't look back at him, instead pretending I was deeply interested in getting my soda. When I retrieved it and looked back he was gone.
I still can't believe that the one time I get hit on, it's at Wal-Mart.
