Pathetic and disgusting service

Today we went out just to have peace,we went to the mc donalds commercial road in Port Elizabeth,eastern cape. The workers were singing from the moment we came in traditional songs,i asked one of the employees to ask them not to sing as we would like to peacefully enjoy our meal, we bought a share box and a big mac meal,the time is now 18:18 we have been here probably 18:00. The lady asked them to stop,but they rep**** rudely and continued to sing. I asked my family if we can leave and just get our order.we are now on our way home,i spent almost 400 of my hard earned money,all we wanted was quality time with my family,but your staff denied us of that. I am disgusted at the level of disrespect and will ensure i never set foot in this pathetic establishment and environment.
