Are people bad at their jobs or are the jobs just bad?

> At Fred Meyer, our local Kroger-owned grocery store, a bagger in his 70s put all my frozen items in a normal bag, and my chips in the cold storage bag I’d brought from home.

A) Having to work a job (obviously not done out of passion) 70+ is really disheartening B) I don´t understand why this even is something that has to be done by a worker. I bought the groceries. I know where I want my stuff in my bags. Or I just toss them back in the cart and load it properly at the car.

A low stress, easy job like that could totally be done out of choice. A big concern of seniors in my life is fearing cognitive atrophy from lack of social connections.

Retail is not "low stress". I guarantee you that senior bagger is getting chewed out every single day both by his customers and his management for being too slow hurry up already, packing the eggs at the bottom of the bag omg what are you doing you fucking idiot, etc.
