<prompt> Human: Hello rpersonalfinance,I would like to share with you a scam that my roommate almost got himself into, until I talked him out of it and read the email exchange. My roommate is planning on subletting his apartment for the summer, and posted an ad on Craigslist. He got a response the same day from a girl from Switzerland. The girl asked him to immediately remove the listing so that he was committed to the deal. She told him she was willing to pay any price, and move inout on any day. The only caveat, however, was that she would have her boss send him a check for more than the amount for rent and utilities for the entire summer, and then he would send back the remainder. On top of this, she needed the remaining money so she could book her flight over here. This meant he would need to send the money back soon, before he could really check to see if the check clears. She also told him to take as much as he needed, with no real set price, and this was before seeing any pictures of the apartment.He thought this sounded totally reasonable, and was about to do it, before I warned him not to and to look into it some more. I knew from reading on this subreddit, that many scams involve sending a check to a person, then having the person send money back before the check completely clears, so thank you rpersonalfinance! I am almost positive this is a scam, and wanted to thank you guys, and watch out for this kind of scam for yourselves!  <response>: This is a super common scam in pretty much any form of business. Send a cheque for more than the amount necessary and then ask the receiver to send some of it back, keep the rest for your troubles. Oh, I cant do it because xyz problems with my bank! Sure enough they make off with the money and 14 days later youre on the hook for the full amount plus overdraft.
