The whole thing is still within the bounds of "extreme incompetence is indistinguishable from malice" so that if the cleaning lady was pilfering on her own account, there needs to be no other malignant actor in the game. It sure felt paranoid at that time, because I had no reason to expect extreme incompetence (nor malice, of course) from a hotel that I had patroned for over 10 years.

As a comparison, Hotel Kämp, which is the only $2,000+ hotel in Finland, also failed in many counts, but I had no reason to expect better, so it was not suspicious, just sad. (And yes, Justin Bieber occupied the small room just next to us.)
