Salad for one? Tiny lettuce is a little sad, but genius

There is an old joke about grocery store cashiers. I remember it only because there aren’t that may jokes involving grocery store cashiers. This is a joke that is in the telling. It’s meant to take a long time with a build up about an extensive series of items being scanned at the register.

“Single, huh?” asks the cashier after ringing up the total.

“Yes. That’s amazing. You knew that just from what I bought?” asks the customer.
