Well, I'm not sure I follow your logic. I am pretty sure that it you ask waiters and gas station attendants, they will probably tell you that this is the job they were able to get.Why do people think waiters and gas station attendants arent christians? They would more likely be christians because they are serving people than the ones in management.
Jesus washed his disciples feet. Staff in restaurants wash your dishes, and gas stations attendants wash your car. What more can you ask for?
