I happened back to the grocery store today, and was in the 2-way opposite-travelling traffic of a grocery store, but stopped at the salmon steaks.
Beside me, in the other tavelling direction, was a woman at a total standstill, with her cart, and nothing to look at on her side.
I looked up and saw an over 50, well-dressed woman at a total hault ...but why? I checked, and an empty cardboard box (rather small, weighed maybe -1#) was in front of her cart. I looked back at her (and there was an employee workiing with emptying boxes) so I reached over, picked up the empty box and gave it a small toss to the store employee's direction, clearing a path.
The N?, 'smiled' at me, began to move, I rolled my eyes at her and went back to choosing my salmon.
Sheesh!
