Ahaha i have no problem of that. Probably i have joined my friends eating too many times at normal restaurant yet i can still manage to go meat-free! I mean like, it's not that hard to request to ommit meat in our meals, right? It's not as hard either for the chefs to do so =P
Yea I had no problems like that before, just that it's annoying when someone knows you're a vegetarian/vegan they automatically assumed that you eat grass and only grass ^^"
