im not following the "news" de jour, so i may be misunderstanding you when you say "cha-ching".
This Neely fella doesnt pocket any of the lodging money. if he cant even claim it via receipt, then he has no opportunity to even get at it. its not like they give us wads of cash, its all on a govt travel card or a personal credit card. if its not on the govt travel card, it doesnt exist. if its not on your personal credit card, it would be silly to ask for reimbursement.
if you're getting at the hotel giving free rooms in exchange for business... well, at least thats a good deal for us taxpayers.
RM (resource management) is tough to work around. hell, getting some new DOORS (regular solid doors) in a few buildings here requires 20 pages of paperwork and a cost-benefit analysis that only a few in our Battalion have the expertise to complete correctly.
skirting rules is /very/ possible, but you have to be a good liar and be willing to take a lot of risk. the only real times having 'juice' matters is when you get caught in your lie. that determines if you get punished according to regulation or are allowed to live another day (figuratively speaking). if others are enabling your lies, it will be even harder to escape with just a warning.
im not saying there are no ways around, but theyre very risky and the benefit (some measly TDY money?) is not usually worth it.
and im a cynic, one who understands the position i've risen to in my favorite Theater is not worth the $15k/yr or so i could (50/50 odds) scam off my various TDYs, or $20k/yr for housing (100% odds, too easy!), etc... there are better things to lie for.
