Bad attitude and *********** staff

Went into the Houtbay KFC yesterday 27 September the buy some ice cream for family and friends. The shop was empty, but there were three customers in the line before me. Apparently there was a problem with the ice cream machine but it was not announced. i would have understood the situation, but no announcement was made. while standing in the queue other customers came in and stood in front of the counter and they were immediately served. when i asked what was happening now. they just ignored me and started the speak to each other in Xhosa and laughed. I then requested for the manager or supervisor. When she came to the front and requested one the staff to assist me , she responded in saying the she was going on tea and she ( the supervisor) should get someone else to serve me. My family and I are regular supporters of KFC and if this is the attitude going forward then we will not be supporting KFC again.
