Manager with serious bad attitude.

Spur, Tygervalley, Bellville. During payment for our breakfast at the above Spur the card machine stopped working. Waiter informed me dont worry it has gone thru. My bank (Capitec) sent message that payment has been made to Spur. I requested my bill and slip and this was handed to me by counter personnel. I left but was confronted by manager one floor down, claiming I have not paid. I tried to show him the bank message but he pulled a FNB paper from the wall and told me to read it. He said that the problem is caused by my bad bank and that I must pay again. He also called me a ***** in front of all the clients and personnel because I walked out of the Spur without paying. I paid again and went directly to Capitec in the same mall and checked my account. I spoke to Capitec personnel who told me the problem was caused by Spur's card machine (FNB)
