Your hard earned money is no good here

Last night I took my son and wife out for dinner to celebrate my son doing well at school. We went to Turn n Tender at The Verge shopping centre. When the waiter came to take our order, I greeted him first and got a half hearted greeting back, no smile or personality. Not once during the meal did he bother to come find out how everything was. When the bill came, the amount was R627. I added a R50 tip for the waiter, so the total was R677. The waiter looks at the slip and then takes my credit card to tap it. Once the transaction went through, he gives a sneer and then walks away without so much as a "thank you". I've been in the service industry for over 35 years, one would think that an upmarket restaurant such as this would educate their front line staff on the importance of making their clients feel welcomed and appreciated. Times are tough and a tip is to the clients discretion, but based on the fact that I was made to feel unwelcomed, I will not be visiting that establishment again.
