They're upset the McDonald's employee isn't the happiest person ever, catering to their every whim. Thats really it. They want us to be little happy bootlickers who work our asses off for nothing.

I complain about young people too but this isnt why. Dont work shitty jobs for shitty pay. If you must work a shitty job, they better fuckng pay up. Isnt that the whole "invisible hand" capitalists love so much? If you can't find workers , you're either an asshole, or not paying enough.
