The hotel rooms are not as clean as the people checking in assume. Most cleaning is done at most in a 15 minute period and lots is reused. Some cleaners don't even use water although they would say they did. I used to work in a hotel which was considered fancy as a housekeeper and the things I saw make it hard for me to stay at a hotel to this day. Faster, faster and faster is the motto for cleaning and if things don't look dirty ...that is fine.
