That's like going to a play and turning your back to the stage. It's insulting and disrespectful, stick to restaurants that cater to vegetarians or who don't care about the food they cook.
Thats not like going to a play and turning your back, thats like taking your children to an amusement park, and being happy watching them do the fun stuff and enjoy themselves.
My actions can be interpreted as insulting when infact they are not. This is why I am offering an explanation. Thats how people live in harmony: they intend no harm, and they explain when they are mis-understood.
