Did you bother to ask yourself why these shops have extra employees hanging around the door? I think there are lots of things that we can't comprehend if we were to live in your country/community but guess what....we just have to be tolerant and move on.

We are here to provide a service hence we should stick to that and stop this “inquisitive” farce of trying to wonder/judge/rationalize why/how the locals behave in THEIR country.
