I was staying at a motel for a conference a few years ago and my phone rings. It's annoying so I pick up.
Him: "Hello, I'm the Regional [something] Manager for [motel chain]. We had some trouble running your card for payment on your room."
Me: "Oh, ok. I'll just head down to the desk to straighten it out then."
Him: "No, ma'am, you need to straighten it out with me now or we will have to call police and start eviction proceedings."
Me: *alarm bells, red flags, sirens, red alert* "Sir, I don't believe you. I think you're scamming me." [wasn't feeling particularly clever/creative]
I don't remember the rest of the conversation, we went back and forth maybe 3-4 lines more, but he tried VERY hard to convince me I needed to sort out "the issue" with him. Eventually, I just hung up and went down to the desk. Phone rang as I walked out.
Someone from another room was reporting literally the EXACT same phone call as I walked up. Tried to make sure the manager would file a police report or something (so at least there would be a record someone was doing this?) but he was very resistant. Not sure if he/the motel ever did anything about it. Sincerely hope no one that night (or ever) fell for that scam. :(
