Worst service ever

I don’t stay far from Shell garage Tlhabane and I must say I fill up time to time there but the service one gets is just horrible the worst it’s unbelievable. 1st they make you wait until you wonder what’s the hold up, then the attendant is angry at you like you forcing him (mostly guys) to do his job then he walks off slowly to fetch a speedpoint machine by the time you done you realise you spent longer you should have. Try to complain and they gang up on you
