I am the guy that runs for food every Friday when we eat out at work. Usually folks look at the total on the menu and give me that amount or so (sometimes I am shorted because they forget the up charge for extra sauce or tax or whatever, sometimes I get more as they give $7 for a 6.35 bill). It usually works out close to even over the course of a year. Anyhow, today I got a couple of pizzas and fries and such. I looked and saw that I had a BOGO pizza coupon from local Entertainment book. So, I used it and now have $10 in "profit" as everyone paid without knowing I had the coupon to apply. Should I be breaking a $10 to refund everyone a $1 or so, so do I just pocket it for next time I am shorted? Thoughts?
