I sat on a plane in the past two weeks.....with the stewardess folks coming around to sell you beverages. This was a cheap-ass flight....virtually everything has a price-tag (even coffee and water).
They offered up coffee to me. I reviewed the deal. You got basically a cup of hot water....packet of freeze-dry coffee (not premium), and a cookie....for five Euro (figure $5.40).
I just started laughing. I'd suggest the cookie was worth maybe $1, but the coffee was crappy stuff. This is how bad the airline industry has gone....selling you crap for a significant price.
