It's now 8:30am on my Monday morning early EWR-DFW flight, and I'm sitting in 24B.
The flight attendants are now to us, with alcoholic drinks for sale, as well as breakfast sandwiches, bars, chips, and candy available for sale. There is nothing available for free. This is a 4 hour flight, and I paid $1,400 for the ticket.
Me: "Um, can I have a sandwich?"
Flight Attendant: "I'm sorry, we're all out."
Me: "That's ok, I'll have a breakfast bar please."
Flight Attendant: "We're all out of them too."
Me: "Oh. Well, what do you have?"
Flight Attendant: "We have some three musketeers candy bars left. Would you like to buy one?"
Me: "No thanks."
