While the Express Lane may only specify that it’s 15 items or less, it is also implied that you will be using credit or debit or some form of quick cash.

Digging in your purse for exact change also needs to be relegated to a regular line.
Almost killed someone at the store today, in case you couldn’t figure that out.
