Similar to the speed test used to test your
internet connection, but this speed test is used to determine which checkout line is moving faster. It involves a snap judgment as to (1) which checkout
clerk looks the least likely to encounter a situation in which they have to call
the manager, and (2) which customers are least likely to have some sort of problem at checkout.
I used the speed test at
Costco and
got burned when the line I changed into was actually slower than the line
I moved out of.
