For all we know, it is a ten-cent tax and a 581.69 for “Having a pilot on the plane fee.”
Reminds me of a story … one day, the old company of a retired engineer calls saying they need him to fix a critical machine. He says “I’m very busy relaxing but I’ll do it for a $50,000 fee” and they agree to pay him. So, he goes to the factory, checks on the machine and uses a piece of chalk to put an “X” on the part that needs replacing. He sends an invoice for $50,000. A few days later, the accounting department calls asking him to itemize the invoice. He submits a new invoice saying:
1 white “X” – $1
Knowing where to put it – $49,999
