Pissing on the street is not wrong as long as you keep away from public fields. None wants to hang around with pee-soaked panty in the heart of city center.
About Qat chewing in day time around the city is something which I find repugnant and we must refrain doing that. It really disqualifies our personal attributes and we must avoid to get adicted.
Chewing Qat is better once in a week at home in good isolated enviroment with your wife around and ofcourse that odour (uunsi) fragrance fumes in the house
but I am not that of chewing Qat on bus and on street and I resist who so ever does it.
