I remember a guest throwing a fit. Cause I called over who was next in line. I know there's assholes who take this as a chance to go to shorter line even if there not next. There's not much I can do. I can't tell them 'you where next' not when there's 6 lanes. Yes that lady wasn't next but unless she visibly skipped you in this line what am I suppose to do? Look I'm just a cashier and half time no one listens to me.
