Fish and Chip Thank You

One of my clients wanted to say thank you to their staff for a job well done - and did so by treating everyone at the works to Fish and Chips for lunch yesterday.  It was such a simple and easy thing to do but the reaction of the team was quite amazing, with 3 cheers ringing out of the factory as the food arrived.  Nice touch, well thought through and relatively easily delivered.    What have you done to say thank you to your staff?
