True, but he was narrating the encounter and continued to do so. I suspect it was some awful vblogger. Normal people don't talk into their phone and explain what they're doing and seeing if they're simply using the phone as a substitute for a key card. Also, most normal people would immediately stop filming, instinctively recognizing it as something that could have legal repercussions for them. BTW, if we knew the name of the hotel, someone here would probably know whether that hotel uses the phone keycards. The hotel front desk could also clarify this and, in fact, they should have records of which guests have opted for the phone keycard.

The laughter from hotel staff is rude, insensitive, inappropriate, and inexcusable. As soon as the guest reported the filming, front desk staff should have called the GM (or at least the assistant manager on duty) and the police. IMO the person doing the filming should have been booted from the hotel at the very least, after verifying that everything was deleted and nothing was uploaded, including to a cloud storage account.

This makes me wonder: Is there any chance that this was a set-up, perhaps arranged by a local colleague? Did the other guest convince one or more hotel staff members that this would be a good joke? Was there any interaction on this or a previous stay that might possibly have given some employee(s) an incentive to arrange what happened?

The hotel won't reveal the other guests name to the OP, but IMO the OP should find a way (lawyer or is there a cheaper way?) to have some trusted person who knows the guest's identity look at that person's blogs, vblogs, twitter, instagram, personal and professional websites, TikTok videos, etc. to check that nothing was posted. This might need the services of a forensic IT person who really knows how to search for images and videos on the internet. I'm disturbed that the guest initially tried to "ghost" the GM and only said that everything was deleted several days later. I think the guest should be able to obtain the GM's email and the person's response with th guest's name, email, etc. redacted.

Since this was a work trip and the OP was arguably the victim of a crime at a hotel chosen by the employer (or did OP pick the hotel?), is there a confidential way to have the employer pay for a lawyer, forensic tech person, private investigator without telling anyone at the company the story of what happened? OP might also want to check whether there's anything in company policy that would require reporting the incident? For example, if an unwanted stranger enters your hotel room (whether you're present or not) and you have confidential documents in the room, I would assume that this would normally require a report to the employer. Similarly, if you're the victim of violent crime on a business trip, I would guess that most policies would require a report, just as you would report being the victim of a crime on the premises of your assigned work facility. [If the violent crime were a sexual assault, the employer should have a procedure for handling this in a confidential way.]

It's too bad the OP didn't record the interaction with guest and hotel staff. It would be good to have the other guest's photo (to identify him and facilitate searching for stuff) and AFAIK there's no expectation of privacy in a hotel lobby, although since the hotel is private property, hotel staff could tell the OP to stop filming and ask her to delete the video. At that point, she could have demanded that the other guest delete everything.

BTW if some stranger unexpectedly enters my hotel room, I scream first and ask questions later. If it's not totally innocuous (and this wasn't due to the camera being used and the failure to immediately exit as soon as it was apparent that the room was occupied), call the police.
