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.

Probably not true at all.

Nonsense. Retail workers have a way of exaggerating how bad their jobs are. I worked retail in my teens and for years and maybe saw 2-3 bad customers in that entire time.
