1. Reading
Task1. Read the text and define the sentences as True or False.
A job of a travel courier
Well, you need to be good with people. I'd say that's the most important thing. And you need to be
really patient. You don't need any qualifications except languages, of course. The more languages
you speak, the better. The good side of the job is definitely the travelling. I've been able to get to
know places I never dreamed of seeing, like Bali and Honolulu. And you meet a lot of nice people
too. The bad side is that it's not very well-paid. The salary is quite low compared to other jobs. And
the job itself can sometimes be very stressful. There are nearly always problems - overbooking in
hotels, flight delays, luggage that doesn't arrive, people wanting to change the rooms and things like
that. The worst experience I have ever had was this awful customer who spent at least two hours a
day complaining to me, and always about the same things. He complained about the size of the
swimming pool, then about the music in the restaurant, then about the food. Finally, he even locked
me in his room one day to make me listen to his complaints. After that we paid for a plane ticket for
him to go home a week early. He was the worst customer I've had.
1) The most important thing about the job of a travel courier is patience.
2) A travel courier should know foreign languages.
3) This job is high-paid.
4) A job of a travel courier can be stressful.
-5) Flight delays isn't the problem that can upset a travel courier.
