I have seen my boss give bill language to a state legislator and then found the same language in print a few days later several times.

Many hotels often sell rooms multiple times. Used to work in airport hotel. Knowing that chances are some guests won’t arrive due to missed or delayed flights so we sell more rooms that we have. You have guests checking out from 2/3 am due to early flights so even though the room is technically still theirs you quickly and sometimes poorly clean the room and tell the arriving unexpected guest or new booking there’s a random computer issue and to wait 20 mins and then check them into the departed guests room praying. Multiple times I’ve had to run a kettle under a cold tap to hide the fact the previous guest used it 15 mins before the new guest arrives - AndromedaFire
