You're paid crappy wages, you don't have a lot of money you hate capitalistic greed so instead of bringing that up to your boss you take it out on customers who might just as well be having a bad time as yourself??? I see this and think its not the customers fault. Example a mcdonalds employees treats customers poorly cause theyre paid min wage when a good portion of there customers probably also are and decide to go there vs save a quick buck. Its like the poor hating the poor it brings out the worst in people and makes you think billionares job is to aid the poor when the poor hate each other and can at times be ungrateful for what they have.
