I'm not saying that no hotel housekeepers have ever stolen. But by and large, we know there's a huge amount of unspoken trust you have to have to let us into your room, and we're not abusing it. We also know, though, that you assume we are. So maybe a little mutual judgment is unavoidable.
Assuming we're your babysitters
This one's more specific to a B&B or a smaller motel with a big communal area, the type of motel where I worked. My housekeeping duties there extended to wider full-property caretaking. That meant I was basically always around (living on the property), which a lot of parents take to mean they have permission not to be. Please don't assume that just because I'm there, I'm going to keep an eye on your kids.
It's amazing how many overindulgent adults that same request extends to -- just, please, drink like you've tasted a beer before. A hotel isn't your college dorm, and I'm definitely not your RA.
