<human>: Summarize the given text in a few sentences.

While at work last night(I work at a hotel) about midway into my shift a guest calls the front desk complaining about a noise in her room. She mentioned it was a constant tapping type noise and couldn't get any sleep the night before and wanted another room. The conversation goes like this.

"I fully understand ma'am, I'm more than happy to try to help get this situation sorted for you and to get the issue fixed as soon as possible. I may have to grab my manager so we can switch you rooms. Do you happen to have any idea what could be causing the noise? Does it sound mechanical or anything like that? 

her "I really don't know, I'm unsure."

me " Yeah, that's definitely weird. Again I'm sorry about you having a problem with this. I'll definitely help you get it sorted. Honestly I have no idea what could be causing the noise, I mean we don't have a ghost or anything like that. (An awful, awful joke to try and cheer her up some because she was upset) a second of silence later I immediately apologized for the bad joke, and then continued with the call to try and get her room switched. 

Later that night my boss finds out about it, fires me on the spot.
<bot>: Joked with a guest at my hotel that I'm sure we don't have a ghost that is causing the noise in her room. Got fired for it.
