Costco gets much of its retail fame from its bulk items and wholesale prices, which can inevitably lead to long checkouts. While Costco claims the average wait time is just one minute, nothing is more frustrating than standing in line with two items behind shoppers with packed carts.

Costco ensures that their checkout lines move as fast as possible by having employees with a click counter at the entrance of the store to track the number of people coming inside. By doing this, they can make sure enough registers are always open, which deems express lanes redundant.
