I've mentioned before my wife is a manager at one of the hotels here on my sandbar, and you don't know how many times I've herd her come home an tell me about the 45 people she had to rekey into rooms. 30 of those 45 were repeat offenders..3 or 4 times they did it before they stopped putting the **** key card under their cell phone. LOL.
