I recently received an envelope that should have contained some room keys...but it didn't. I know of a few other people that have had similar experiences recently so I'm thinking that I need to make a greater effort to conceal what's inside of the envelope. I used to think that no one would be interested in a little plastic card inside of an envelope. I suddenly realized that with the holidays approaching, people are sending gift cards as presents...and there are probably people out there ready to jump at the chance to steal this "plastic cash". When they open our envelopes in the hopes of finding a $20 giftcard, they're disappointed to find a "silly" room key or slot card and they probably toss our treasures in the trash.
Just a thought I wanted to share as we approach the holidays. It's better to be careful than sorry.
