That's totally NOT how it is at our Sam's Club.
Yes, there are some people who travel past in the aisles that are not 6 feet away, but at least they are wearing masks. Not a lot, but some.
They've installed plexiglass barriers at the check stands.
The cart unloaders are still there, but you can ask that they not "help".
At the door we have to hold up our receipt for the door checker to scan the bar code on it, and then they scan the bar code one of the items in the cart (there's usually one on top).
There's also senior hours, and valet pick up available during those hours. You drive up, give them your shopping list, and a employee gets your stuff, brings it back out to your car and unloads it into your trunk. Only contact there, you have to put your credit card into their reader to pay.
