Extreme rude staff

Earlier on tonight we stopped off at pick pay Northmead mall to get some items on our way home from work at first we go to a cashier to pay she shouts at us after politely asking her if she's open she shouts nooooo we then went to another cashier to pay not even a smile or a greeting from her I then say hello she just looks at me as if I'm invading her space rudoy she ses to bag not t even would you like a plastic bag I say yes pls grabs my card out of my hand Taps obviously very up set she has to work now I am a business owner never would I treat customers that way never teach your staff etiquette and manners never will I go there again would rather support checkers up the road
