Totally agree- have seen the vibe you describe above at numerous restaurants lately. The part that saddens me is the food recipient tends to take it out on the delivery person, "Food was cold!! ZERO STARS, NO TIP!!" when in actuality that person was given an impossible task- to deliver more food per hour than the laws of physics over time and distance would allow without teleportation.

I work in property development and also see this happening more and more frequently for contractor and appliance delivery people... instead of showing up to deliver your appliance, they mark you as "not home" or "unavailable" and skip attempting delivery or install altogether- that way they get to bring the stuff back to the warehouse, don't have to bother wasting time attempting to delivery it and the guy on the next shift has to deal with it.
