Speeding through the self-checkout
You may feel pressure to get through the self-checkout lines as fast as possible, thinking that it saves everyone time and makes the line move more quickly but it's more helpful if you slow down and take the time to follow all the instructions, says Thomas H., who works at Sam's Club, in Utah. "Ninety-nine percent of the problems could be resolved if customers took the time to read what was on the screen (i.e. scan an item again, use the other barcode, tap here for printed receipt, etc.)," he says, adding that it's fine to ask for help if you need it. "You're not wasting our time or inconveniencing us, that's what we're here for," he says.
