A: I missed my connecting flight to Washington D.C. B: How did you miss your flight? A: I was sitting in the airport bar and I lost track of time. B: Well, that's not really our fault. A: Fine, but what can you do for me? B: I can put you on the stand-by list. A: What does that mean? B: It means that if there are empty seats on the next flight out, you can get on. A: What if there are no seats? B: You can buy another ticket. A: I didn't even buy the first ticket. B: I guess you have to buy a ticket.
