Poor service from certain staff!!!

On Saturday My mother, my sister and I went to fashion express shoes in Promenade mall.. Upon arrival in the store there was a short light in complexion girl at the till assisting a customer and may I add this girl gives us excellent service everytime we walk into the store.. When we came in Maryke was sitting on the white display thing with another girl with longish hair. I then went to the boot that I wanted and the size 6 didn't fit me.. I then requested a size 7.. the poor girl at the till could obviously not get away and called maryke as the other girl was apparently OFF DUTY! Maryke then came on her own time and asked what size I needed.. I said size 7 and without even looking she said ? don't think we have that size\ there were two diffeen kinds
