sms: Which country do you come from? In all countries of the world there exists no such laws which segregate humans. Take your own country as an example. You are just too fussy or oversensitive, that's all.
Possibly, you are unaware of the complete rules. People working in shops or restaurants or baqalas who have their business in in a locality can stay in that same locality where families also reside. And that is legally. Just look around your own area. There are such people living in all areas.
It is simply illogical and not possible for people to be running baqalas or shops in say in Al Rayyan and be residing in Wakra or Wukair.
The bottom line: You shift!
