Gambling addiction is so crazy to me, I could never tell if anyone was addicted though at the counter. I used to work at a pharmacy with a lotto machine so that probably determined customers a bit. The older retired ladies coming in with their pouches was kind of charming and they weren’t very big spenders overall, they seemed to just enjoy organizing and managing it all.
Slot machines in casinos really affect me in a depressing way though, seeing rows of people just pressing buttons over and over while they stare at the machine I find disturbing.
