Bad attitude

on the 06/Feb went to purchase something at Mr Price, joined the queue, the person who was infont was done and left the counter, I then made my way to the counter and the cashier was busy scratching and tying her hair, I stood there and waited, the other cashier was done serving a customer so I asked it she can help because I see Ms Beyonce is still busy with her hair, Ms Beyonce just told me it will help e if i o to the 2nd cashier as she did not call me, she is still busy, I asked her if is this a salon? she then rep**** saying \You are the customer you should wait to be called"And she was still busy tying her hair while I was talking"
