Headcanon that Hanzo got a job in a store once when he fell on hard times and he lasted literally three hours before he told a customer that if she didn’t control her horrible children he would personally kick them out of the store. Literally. Using his sharp metal prosthetic feet.
Jesse was really sorry to have to fire him - his new best friend for sure - because it was the best thing he’d ever seen, but thankfully Hanzo accepted his offer of a place to crash until he found his feet again. He also smiled widely when Jesse followed it up with an offer of dinner and a movie.
Maybe Hanzo just wasn’t cut out for retail.
