It's five o'clock in the morning and passengers are called to gather at gate 12. Paco is on the line and just in front of him there is a girl who has lost her boarding card, she is talking to the air assistant despairingly...
Air hostess: Sorry madam, but unless you have your boarding card you won't get on the plane.
Girl: But, I can't find it. Maybe it is on the chair I was sitting.
Air hostess: Well, you can go there and look for it. Providing that the boarding pass is there, you will get on the plane.
Girl: But what happens if I'm late for boarding.
Air hostess: Don't worry madam, if you are in a hurry we will wait for you.
Girl: Well, I will go then, thank you.
Air hostess: Welcome!
