When you go out for a meal with 'new' non-vegan friends, what do you usually say about why you're not having meat/dairy? How often do you use the old stand-by i'm allergic ..LoL! Will you wait until people start asking Q's or do you tip them off in advance? How often do you ask your waiter if their are any animal by-poducts in the 'dish' you want to order etc.?
