Costco staff treats customers like criminals. I totally understand that you need to show your membership card when entering the store. At the self checkout they ask to see it again and the staff is all around you looking at every move you make. And let’s not forget they have cameras everywhere, at the registers, top of ceiling. So what is the problem? Then upon leaving the store they go out of their way to count every item in the cart like three times. I have never been treated this way at any other major store. Costco staff need to take some customer service courses to learn how to do their job effectively, with a smile and not make their customers hate their shopping experience.
