Well if you only want to sell to vegetarians, then you should put that in the advertisement (mention about the neighbors and neighborhood being vegetarian).
I don't understand why though, especially consider the number of vegetarians who go back to eating meat (just read Peta's celebrity watch column). Or wait, is that why you have to move out of the neighborhood? You didn't start eating fish and they kicked you out, did they?!
Neat temple there though eh.
