Because the teenage wage slave at the register doesn't give a shit about your fine distinctions.
When I worked that McDonalds the machine was almost always down simply because the night crew didn't give a shit and it was too much effort to clean. I worked mornings with the old folks because I was too uncool for the night shift.
hey now, most of the people I see working at McDonalds are fully grown wage slaves. Chick Fil A and In and Out seem to be the main purveyors of adolescent labor these days.
"Good sir, it appears that our ice cream machine is down for scheduled maintenance, can I interested you in a piping hot apple pie perchance?" - teenage wage slave ;)
