Where has CUSTOMER SERVICE gone to these days.

My family and I went to do our weekly shopping at Watercrest Mall this afternoon when my Mum wanted to sit down and have something to drink. I was with my kids who just wanted a milkshake. Upon our arrival it looked like the shop was ready to close. (Around about 16:45). The waitresses were behind the counter cleaning condiments and having a jolly good chat. No one greeted us,we sat ourselves down and eventually a waitress sauntered over with some menu's. We tell her that we only wanted something to drink and that just seemed to change her mood. We ordered coffee and milkshakes. It didn't take long but then it was delivered to us by another waitress (Ntokozo) she didn't even greet, or even smile. We asked for more serviettes and they were slammed down on our table. We then ordered a waffle for my kids to share and a apple tart. NOT ONCE did the waitress come and see if we were okay. I had to get up and ask for the bill. At the counter I wasn't even greeted the bill was printed and slammed down on the counter top \there's your bill". 3 waitresses behind the counter and not even a hello or a SMILE. It wasn't even BUSY. So disappointed. I tried to call Gary Schwin....but got no ans"""
