Recently eating meal outside a restaurant. Family arrived to eat outside. One parent went to nearby fast food chain and bought food for one child and brought it back to eat at this restaurant. Waitress advised politely that it was not allowed and parent needed to order drinks and food. The parent had not thought to ask if it was on to bring food from another restaurant first. The family left. Why didn't they all eat in the fast food place ? Or some eat at one restaurant and some at the other restaurant. Im assuming no food allergies. This just seemed very rude
