Bad Attitude and poor customer service

If the chicken saga with this KFC wasn't bad publicity enough, the attitude of the staff has gone from zero to a negative zero. Yesterday I had to stand in line for almost 20mins to order ice-cream, mind you there only 3 customers in line and I was first, eventually we got to order the 2x ice-cream sundae, whiles waiting 3 more ppl ordered meals after us and as I realised that the person after me got her order I asked the lady politely what about my order, with an expression on her face told me that it's being done when I clearly could see there was no one next to the machine preparing them, waited 20mins again as she went along assisting other ppl with their orders and to top it all of giving them ice-cream. As I asked her once again she only then called out to another staff member to make the sundae. I was completely, utterly disgusted and requested my money back, the manager was called and OMG, he came no apology and was handing out my cash, with that said he asked \rhirandzu"staff member why the order was not made and she lashed out at him saying \""please don't mess up my day because I was busy\"""
