I'm filling out an expense report, for reimbursement. The largest item is a product I bought from a company named "Mountain High", in Oregon. I'm going to place it in the hands of a yoga instructor, who will inhale through it. And I thought it was weird expensing cases of beer to pay for northern maintenance.
Mind you, this is an oxygen mask, not actually a joint. And you'd be surprised by the things people who fly airplanes are certified at besides piloting.
