    The bathroom had no soap or sanitizer (was out), which immediately raised a hygiene concern. It made me wonder where the staff wash their hands after using the restroom. Because of that, I didn’t feel comfortable eating the meal and ended up leaving my food.

    Yesterday I was in Popeyes, the same thing, the service really bad, especially when someone like me trying to get something to eat, those employees prioritize drive-thru costumers and orders they place in advance online. You have beg for service. They're in a bad mood perhaps frustrated, I really don't know we had to wait a long time before we got the order.
