I worked independently at a gas station for a little over a year. Shift changes would occur after 8 or 9 hours. Noone ever told me that I couldn't eat, or go to the washroom or go for a smoke outside. However, it was understood that if a customer walked inside the store during eating or having a smoke, you would have to stop and deal with the customer. Bathroom break meant locking the door and putting up a sign. I ran the risk of losing a customer because of a bathroom break, but no employer was ever going to complain about that to me.
