@dougsportazine A lot of it can be mechanized away, but much of it is human-interaction. As anyone who's been through one of those voice-prompting systems knows, #bots do not do customer-oriented #human interaction very well. (Which could be why @x11r5's #bot_in_the_house campaign hasn't gotten vote 1 yet. But that's a different @question.)
Anyway, I found during my college years that working in "quickserve restaurants" was more difficult work than digging up and potting trees in triple-digit heat (and required more customer service skill than my current customer-oriented job, though I got a fraction of the pay I get today).
