Not tipping housekeeping
Being nickel-and-dimed by a hotel is nothing new, and the last thing hotel guests want to do on their way out the door is pay more for their stay. That sentiment leaves the housekeeping staff… well, nothing. Housekeeping is the only traditionally tipped staff you never see (as opposed to the bellman, valet, or wait staff), so guests can escape without feeling cheap. Those sad little envelopes -- which ultimately serve as a reminder to tip -- are hardly ever used.
