Well....it's his money and his time.
But with that kind of unlimited expense account, OP, you could have visited Thailand or Cambodia and had a whole bunch of grade A quality steaks for a whole 2 or 3 weeks.
But it's always a losing battle trying to show someone who is already knee deep in the sunk-cost fallacy.
The more anyone else suggests other options, the more hardline, and defensive someone can become.
Anyways, good luck on your next adventure.
