Time to boycott. Even if just all the Slashdotters boycotted, it'd be something to see. Or perhaps organize a drone-enabled protest outside..
These jobs used to be filled not just by school kids and retirees, but by anyone looking to get by or pick up a little extra cash. Today there're more and more people clinging to these jobs as their last hope. Things have changed. On 'our' side, its gotten worse. On management's side? Well, let's just say that if the minimum wage had kept pace with the cost of living from 1978 on, $15/hr would look like a sweet deal to them.
I'd gladly pay 2 bits more for a burger knowing it was going to a real flesh and blood person rather than to grease and pneumatics upgrades.
Anybody feelin' the Bern? ;)
