I'll fake a hotel receipt when I'm doing a mattrss run on business.

They wouldn't understand why I'm turning in five different reciepts for five different nights at five different dollar amounts (even if I was only asking for the lowest amount back) so I'll download the rate I'm asking for off the website, open it in photoshop, and make it for five nights at that amount. It's probably technicailly not fraud, because the amount is the actual rate (actually it saves them money, because I always choose the least expensive rate), but it's entirely done to aviod questions.

At a previous job we would always collect blank restaurant receipts no matter where we were, we had a little fish bowl of them, and when you needed a restaurant receipt, you dug through the bowl until you found one from where you were visiting. That really wasn't fraud either, they knew we were doing it but still required a receipt for each meal.
