Snarling trolley boys! (reminds me of "they're only words")
True - it would be - most of them don't pack well anyway - my first over the table job was as a bag boy- and I was very good.

Trouble is, now - I am too concerned with what the cashier is charging to take my mind off the register and to my own bagging.
I get too stressed at the store with all the people- I am constantly trying to not be in the way - yet everyone else is constantly in my way, too. So I avoid grocery shopping.
(but my French pal did say that the shoppers here were much more polite than in France

)
