I got a nice full date '35D or '36D buffalo nickel from a Subway restaurant several months ago myself and I got a 1918 wheat cent from McD's earlier this month. Nice unexpected surprises.
I got a couple of wheaties in change one day when we left our local "greasy spoon". If I had realized that 2 of the coins were wheats, I would have asked her to look for more in the register.
