Anecdotal, but my partner recently went to a lake house for an engagement party. The lake house is a touristy location, and obviously meant to be a vacation home. However, the renters would only list the property as a "meditation retreat." Meaning no alcohol, no noise, no day guests, no fun. They had beach chairs in an unlocked area, and after the weekend sent a $900 bill to the guests. Apparently even though the chairs were freely accessible, using them constituted rental, so they charged $50 per chair per day. How else did they the host know they used the chairs that many times if they were not spying on them somehow? I imagine if they actually did anything, that bill would have been higher.
