Beware... this happened to me.

It's almost 1a.m. in Fort Wayne. I just got finished walking downstairs to meet the hotel desk. Why? Because I received a phone call from a man reporting to be from the hotel and claiming the hotel had a problem with their computer. He stated he needed information from me to confirm my reservation at the hotel. I gave no information, hung up, and walked down to warn the hotel desk staff. This was not an isolated hoax according to this BBB news story.

Be warned the world is full of people who want to steal from you.
