When I have to open the door- and the door opens towards me- I will use my coat- a receipt- the inside of my shirt- a pen that I found in my purse which is laden with the remains of a piece of Trident Gum… or I will Cirque Du Soleil my foot into the air and hop backwards and then shift my ass to the opening and “hip” push the door wider.
I say all those things because there is always another way.
If I were a cashier person and had to break the hermetical seal in order to bag someone’s items, and it was Covid time… I would sooner stab myself with a pen and use the blood to open the bags- than I would stick my finger in my mouth and lick my fingers!!!
