If someone has strong food preferences and/or allergies....stay at home.
The tyranny of one.
Phooey.
“If someone has strong food preferences and/or allergies....stay at home.”
This is the correct approach. These restaurants should post signs that clearly state that their food products contain ingredients that are not kosher or halal or anything of the sort. It is bad policy to try to accommodate the muzloid cranks and crazies for a few measly bucks. Better to head the problem off at the start and keep them from coming to the restaurants at all. I like that better, anyway.
