Honestly, I've never fudged receipts. I used to bounce from HHonors property to property at a 50k-per-4-night clip, but I always turned in the correct receipts. Since I always did it at or below our corporate guidelines for hotel rates, I never got questioned. I would've told the truth if they had asked me - no policy against changing hotels: what is there to hide?

I frequently carried a stack of blank cab receipts, but I never abused them. I simply used them for specific instances where I either forget to ask for a receipt or where I was paying cash and in a hurry to get out of the cab.

We had fixed food per diems on the road so the $25 meal rule was not an issue.

Everybody I've worked for has been very cool about travel, so I've never felt the need to scam a few bucks here and there. I've always had the liberty to pick my airlines, hotels, and rental cars within the scope of some common-sense guidelines. My employer not only encouraged us to play the FF game, they automatically submitted the sign-up forms for most of the programs I'm still active in today.
