On your question:

"Do foreigners - non muslims not have the right to have the meat they want to???"

Sure..but majority of the people shopping at these stores are Muslims. I can guarantee you most Desis would flip out if they knew that the meat here was "Jhatka" meat as they say! (literally shock meat where animal is killed by electrocution)

At least label it.
e.g. if you go to Dubai, Jordan or Egypt and they have the Pork and alcohol items marked very clearly on the menus.
