So, this happened a while back but I still remember the experience for being incredibly stressful. I was working front desk in the late evening, when a caravan trailer parks outside the property and in come an Irish couple and one of their friends.
I find out the couple has a reservation and their friend is just escorting them and is staying in the trailer. Everyone at this point is very polite and jovial so I did not expect what's to come. The couple checks in without issues and their friend asks me if he can stay in the lobby for just a bit to chat with his friends. I allow it since the guy seems harmless and all.
The trio then moves to sit on couches in another lobby area that is away from the front desk and it does not take long for things to get out of hand. I get complaints about this group being very loud despite it being quiet hours. I take a quick glimpse at the security camera and see that this group of three had increased to a dozen people and a dog that were causing a huge mess in the lobby with food and the packaging of said food thrown around the room. Apparently the caravan contained way more people than I thought.
At this point I have to go down there myself. I very politely tell them that hey, it's quiet hours and that they cannot cause such disturbance and also that while I allowed that one guy to hang out with his friends, this amount of people is a bit too much. The polite guy from earlier suddenly goes insane and springs up from the couch straight to my face and says that they are not going to stop and if I try to make them stop, the dog is going to rip my throat out.
At this point, I am quite nervous, but tell him that he crossed the line by threatening violence and that now the only option is for him to take his entourage and leave. I was planning to allow the couple to stay since they had a paid reservation, but at this point they also started shouting insults and profanities at me so I also told them to pack their stuff and get out. They told me that I shall not kick them out as they are leaving of their own will. I thought that whatever works for them as long as they get out.
So in the end despite all the threat and profanities, they leave. I go into the empty staff area to vent out the terror I was feeling a moment ago as I realize how fortunate I was that they were all bark and no bite. If I had expected trouble, I would have taken a security guard with me, but they seemed like okay people at first.
The next day the couple returned to complain about the treatment they were subjected by me. Apparently they were the "good guys". I wonder if with that behaviour they can stay anywhere.
