Ironic they have plenty of "hotel bad because smoke smell" and none of the "hotel bad because of fake smoke detection fine" testemonials on the site.

They also cover vaping. While smoking harms are clear and its impact on room smell is evident, the connection is pretty weak for vaping. Unless it’s a crowded bar with lots of vaping people, I can’t tell if somebody has previously used an e-cigarette or vaporized anything in a room, and generally speaking I don’t find such vapor disturbing (altough the smell can be not great).

I found that people vaping around me causes minor irritation in my eyes, and I also find the smell rather annoying, despite my sense of smell being rather weak.

I haven't noticed any long-term effects on rooms with frequent vaping though

I'm curious how various court systems would handle a person suing nearby vape users for (documented) minor irritation of eyes and airways.

If such suits were successful, would the newly tested liability set larger changes in motion?

I'm similarly curious about being around Amazon Alexa, etc. devices in circumstances that require two-party consent for recording audio.
