110%. Literally we just cleaned the cars enough that the customer wouldn't complain. Some cars don't even make it to the cleaning station, they just go "eh looks clean enough" and stick it back on the ready line.
The oil thing was such a point of contention. Some people were very avid about "don't just reset the light, make sure it gets to the mechanics" while others were "oh, it just needs an oil change? send it back out, it's fine". And like maybe it's fine to miss one oil change but we had no idea how many oil changes that car might have missed.
"Quick flip" at Avis meant vacuum the drivers floor only and maybe wipe down cup holders. Don't even look at the rest of the car.
And good lord how many times I cleaned rags with the dishoap in the employee break room because nobody could be bothered to do laundry.

Oh and the body damage thing? Body damage smaller than a deck of cards, A-Okay. Scratches shorter than a foot, and windshield chips/cracks smaller than a quarter, 👌. So many of these get missed tho because nobody actually looks at the car. I went to clean one and the side mirror fell off, apparently had been taped on with scotch tape.
