Ella, 33, restaurant manager
The first time I did this I really didn't do it on purpose, but it worked so well I tried it again. I was having lunch by myself and I realized I'd forgottten my card and hadn't got any cash on me. A guy heard me saying I'd forgotten my card and offered to pay for my meal if I took him out for dinner next time! I said yes because I didn't really have the choice. Nothing came of it, but if I'm ever eating out on my own and I want to try and fix up with someone I'll definitely try it again.
