I paid $200 for a meal once while on TD and claimed it. Why? I was nowhere near a base, it was 2200hrs and I hadn't eaten since noon, and the only place open was a wine/jazz bar that happened to have a grill open that late. I also reemed the hell out of the Travel Coordinator for scheduling my travel in such a way that I put in that position.
In the end, I needed to eat and I was stuck paying for the availiabilty.
