Many a good business has been ruined by poor staff PR.
It sounds like the good reports generally come from those who know the owner, which will mean the front desk crew will not try anything on with them.
Have to say, its the bad reports here that discounted PV as a potential hotel to stay for me on my recent trip (why risk the possible hassle).
Considering how many guests browse this place, potential trade lost could be huge, so someone should have a word with the chap if they can.
