I'd rather have them go topless than tipless as I prefer full serve and have no problem tipping 25-50% on a regular basis.
One time I was at the grocery store and decided to try the self checkout lane at like 11-12 p.m. when the store was dead. 3 cashiers sitting on a bench talking watching me self checkout. Felt like saying get up bitch and do this shit. You can keep the manual labor if I wanted that I wouldn't be going out to eat.
