I know this was a while ago but it's hilarious to me that you think the cashier should have been fired on the spot when she was just doing her a job.Let me educate you on the light system.
Light ON register OPEN light OFF register CLOSED. How complicated is that? Theres not always a lane closed sign at every register. And she didn't have to take you.
Go somewhere else and move on with your life. The whole point of the light is to signal when a register is open.
So saying a light off doesnt mean it's closed?You're dumb.
