I recently dealt with Sam's Club for a work event I helped put together. We ordered 2 full sheet cakes, and shopped for various stuff for the event in the store.
It was easy to find everything, they had a good amount of stock, and the employee presence was noted. In the bakery, the one guy was really responsive and ordering the cakes was not an issue. I believe there was a mis-communication on some minor details on the cake, but that was my fault. It still turned out beautiful and delicious.
Check-out was fine, cashiers were appropriately friendly, and I have no complaints.
