Is not proving washcloths becoming normal? [USA]

I've stayed in two Airbnb's in the last three months and neither has provided washcloths. The first I just assumed it was an error, but the second has me wondering if this is becoming standard practice.

I just find it strange, especially with what they DO provide. Clothes detergent, dryer sheets, dishwasher tabs, propane for the grill, shampoo, soap etc. - but no washcloths?

It's not the end of the world, I guess I can just buy a pack of cheap washcloths, pack one and toss it at the end of the trip.

What gives?
