Terrible customer service at check out. I put my Costco citi card & then started unloading items from my cart on the conveyor belt. This guy who was supposed to be helping me unload the items comes & rudely tells me to go behind the counter with my card. Almost like scolding to some little kid.. Wow!! I did & stood there behind the glass counter waiting for the cashier to hand over/show my card. The shopper who was ahead of me leaves & I continue to stand behind the glass counter when the cashier started scanning my items that I had unloaded earlier. Meanwhile this rude guy tells the cashier to tell me to unload all the small items while he just hangs out there doing nothing. I unloaded all everything from my top cart one by one & some from the bottom (all just groceries except one cleaning item I had today). I was embarrassed & furious at the way he treated me. He didn't even ask me if I wanted any box & made no eye contact. After he finished putting all the items on my cart, he hardly pushed out my cart & just turned around. My total bill today was almost $300. I don’t know why he was so grumpy, mad, unpleasant & rude to me. It was only around 11 in the morning & he can’t be exhausted already. I looked to see his name tag & ofcourse it was flipped around but I managed to see it. He was TONY. Unacceptable behavior & I will always avoid him in the future. He needs some training for sure on how to behave while at work. The cashier lady was nice.
