Maybe people want to eat where it’s LGBT-free. Who wants to eat a transgendered chicken? It’s why I like to eat at barbeque places - no Muslims!
Actually you may see some at a BBQ places but they would be there for the same reason you would. There is an exception to their no pork rule. If it’s the only food around and they need to eat it to stay alive then they can eat it. But they must do extra prayers after. So when some Middle Eastern visitors come here to popular BBQ areas they will purposely drive to an out of the way BBQ joint and eat there because it’s the only food around.
