I don't even bother with the checkout line at Sams. I go straight to the door, they scan my phone and I'm off. If I'm not buying meat and such I don't even go in the store. I just pull up and they load my order in my truck.No matter how busy Costco is, no matter how many people in the checkout line, they will have plenty of checkout lines open, and when it's really busy they'll have at least 2 and sometimes 3 people working the checkout. I've seen one employee taking things out of your cart and putting them on the conveyor belt, the cashier scanning them and a 3rderson putting your items back in your cart. They also work much faster and harder and quicker than Sams. Sams will only have a couple checkouts open, lines taking too long to move up, and one slow as molasses checker doing it all.
