Rude sales assistant

Rude and grumpy sales assistant. I was in there yesterday to scan docs. 2 ladies behind the counter 1 super friendly and trying to be polite with the customers. I was being helped by the male assistant and standing at the counter when I was quite rudely brushed off the counter and told to "have a seat so long" I was quite happy and comfortable standing at the counter and waiting. Her facial expression was telling that she wants a better paying job. Or the navy scarf she wraps around her head was tied too tightly. Her face chases customers away.
