I think I told this story to Brad Gosse during dinner - my sister has been a vegetarian since she was 5 (she's 29 now) and was vegan for a few of those years. We went to a country restaurant a while back and she ordered beans, not realizing they were cooked with pork. We being the mean siblings/family that we are (we many times order veal just to watch her squirm ;) ) didn't say a word.
We all had a good laugh when she kept saying they were the best beans she'd ever tasted in her life
She's been living with a non-veg for a few years and he's slowing bringing her over to the dark side.........we like him ;)
