Yay! New thread. I don't have anything to add since I've had the joy of not being at work for the last 2 months, although....
I was home over Easter and working, we have a dual lane drive thru so it gets pretty busy, and I had a customer come through and try to order, with the way the system works I have to take money before the next order or I get shouted off. Anyway, since I told this guy that I'd be with him shortly he decided to start counting the seconds in my ear while I was trying to deal with the customer at the window. I wound up taking the headset off and possibly taking a bit longer than necessary taking money...
Definitely not the most annoying customer I've had but it's late and I'm meant to be revising so it'll do for now!!
