What can I do for you, Sir?
I'm Tom in room 508, and I want a wake-up call tomorrow morning.
At what time?
6:15 am, please.
No problem, we have a computer wake-up service. Please dial 2 first and then the time. That is to say, dial 2 and then 0615.
I see. I should dial all the numbers 20615 in turn. Thank you. By the way, if I want to change my wake up time, what shall I do?
Just dial your new wake up time, the computer will record the new wake up time and delete the previous numbers automatically.
If I dial 20700, I will be waked up at 7:00 am, am I right?
Yes, quite right.
Thank you. Goodnight.
