It's true in the beginning the hotel worker was painted as a saint.
But Bill's question brings food for thought.
I find it hard to believe the hotel worker with a name tag and uniform on tried to rob them by knocking on door to fix stuff.
Maybe a party went wrong.
Some people step out of their comfort zones on vacation, some experiment with drugs they never tried or some play bedroom games with strangers. ( very common on sxm)
Or maybe the hotel worker really went mad on that day and set out to commit a crime for which he would surely be caught.
Who knows what really happened.
We may never know the truth.
