Rude lady owner or cashier

There is a rude white lady who talks to customers as if she is talking to her little kids.She needs to adjust her attitude very quickly otherwise she might be losing a lot of customers especially in this current climate.On Tuesday the 11th of August she beckoned to customers with a gesture of rushing them towards the counter with "come come ""minus even a greeting,who does that to customers.On advising her to revise her manners she told me that I talk too much to which I left the store and went to spend my hard earned cash somewhere else.At this rate that business will be out of customers
