When a customer gives you a Food Stamp card that is lying face down; politely return the card back, in the manner, in which it was found.
Don't put the bread, in the same bag that you have for meat.  An angry customer may get mad, with a desire to knock you off your feet.
When lying the customer's groceries down, don't throw it as fast as you can. You can break what's in the bag; depending on where it land.
When giving the customers their money back, patiently count it out.  You will have peace of mind, and that without a doubt.
Treat the customer with a smile, try hard from looking mean.  You will always come out on top; your record will end up clean.
