Rude 60/60 personel at Checkers

I really need to ask this question: when interviews were done with the 60/60 staff, were the most rude ones picked for the job? I normally go to Checkers Hyper Roodepoort and they have 60/60 staff with absolutely no manners, respect or consideration for other people. I was busy getting fruit and this person doing the 60/60 stock, physically pulled my trolley away to get something before me. They will also push you out of the way to get something on a shelve or just bump you to go past as quick as possible. I stopped going to Checkers because of that previously and went back today, just to get the same happen again.
