Here's a simple one: took a girl out after a few conversations at the bookstore I worked at. I told her Hey I Have A Coupon For Coldstone, Care To Join Me For Ice Cream? She said Sure! and we went out after my shift. So we got there and I ask her What Would You Like and she said Oh Nothing I'm Vegan. I could [i]feel[/i] everyone staring at me, as if to say Are You An Idiot?!?!. We ended up sharing three sodas instead and she never went out with me again.
