I love Costco. But this location isn't representative of what Costco is in other nearby locations, particularly the customer service at the service counter.
Went in there today, and while perhaps the employees (I talked to two of them) couldn't actually help with what I needed, the attitude was dismissive and borderline rude. I don't expect everyone to be able to do everything all the time. But at Costco I'm used to employees being quite nice and helpful, even when they can't help with what you need. Not so today.
Service in the back of the store, the cashier, and the food area employees were great. Just a couple of dismissively crabby and unhelpful folks at the service counter.
