Unpleasant experience with your employee who requested a bribe

I sent my brother to engen garage on the 29th of June for gas refill he got there and found a queue upon arriving the attendant that was there asked him for R50 in order for him to get him at the front row which my brother advised he does not have and he kept on pressing him till my brother said i will buy you a drink rather he want inside and took a 1.5 litre drink which my brother paid for but he seemed angry he did not get the R50 he had requested fast forward to today our gas is finished and its not even a month a gas we normally last 2 months with meaning this guy did not fully fill our gas probably he filled it halfway.Very very disgusted by this service in Tableview Capetown.
