Rude cashier - not the first time.

While in a queue at Game, Bayside Mall, next in line to be helped, the customers in front of me had an issue. The cashier, without saying a word or acknowledging my presence, picked up her "closed sign" and pushed it onto the conveyor belt pushing my product away, still without a word. I continued to stand there, waiting for a polite "Sorry mam, we are having an issue and might be a while"or something of the sort but got none. I asked the cashier what was going on, she rolled her eyes and mumbled something looking in another direction. Please train your staff to just have manners and common decency. Not the first time I have had rude service here!
