I used to work retail too Babs.
I was the HR MGR and my job was to have all the holiday hiring done by around Thanksgiving. So then I could help out in gift wrap or help on floor (after payroll of course!)
One year I was recruited by the Store Mgr to pass out these coupons at the door. We were an anchor store so we opened at the butt crack of dawn.
I couldnt believe how crazy people were. I was almost attacked!!!!!
Now I am close to 6 feet tall, so its not like I am some teeny person - they about knocked me down!!!!
I feel for all clerks during the season - and I remember that as I stand in line and wait and I give them alot of smiles or comments to encourage them.
