Continuous bad attitude at Checkers till

Almost everytime I ho to Checkers, which is a lot because its the only big supermarket in Tzaneen, Limpopo, I experience a very bad attitude regarding client service at the till point. Most, not all though, of the ladies working at the till have little respect for customers. I really think Checkers needs to pay attention to this. If it happens to me, and I'm a very friendly person, it must happen to everyone. Its like they are doing the customers a huge favour. Very dissapointed.
