The accountholder is required to show it, It is in Costco's terms and conditions.
I live near, and commute by, one of the PNW Costcos in the PDX area the author explicitly references. I can confirm that just the mere sight of the parking lot, at all hours, has been the primary factor in my refusing to get a membership. Plenty of friends and family I trust love Costco, and I'm sure they're right and that I'd find lots to appreciate, but that damn parking lot madness is such a hump for me to get over.
FWIW, I'm referring to the Beaverton Costco right next to Nike.
I also don't like the door check 'game.' Additionally, being hounded at checkout to upgrade your plan while juggling a 5 year old, dealing with payment, and a line full of people behind you is not enjoyable.
I don't know what Costco parking lots in the PNW are like but in the NE, they're a nightmare. People racing around, lining up and jockeying for spots, enormous carts careening around and being left ... wherever because people can't be bothered to put them back. My family has a membership but I permanently opted out after one trip to the Danbury, CT location.
> otherwise you are rarely confronted by the staff here, and I like that.
That is, until they try to stop you from leaving the store with your property until you show them a receipt.
