A: Hi 

B: Hey, how are you?

A: I am ok. Why are you looking on your phone screen all the time?

B: I am checking my app

A: Your app? What kind of app?

B: I have got a new app. It's called 'wag' and searches for dog walkers.

A: Dog walkers? But you're not a dog walker, are you?
B: Yes, I am. I have been a dog walker since last Saturday.

A: How does it work?

B: Well, people who need someone to walk their dog put a message on the app and then I can react to it. 

A: What do you mean 'react to it'?

B: I can make contact with the one who wants his dog walked.

A: Why would you do that?

B: Because it earns money.

A: Ahhh, now you got me interested! Tell me more :)

B: So you get in contact with the dog owner and arrange the time that you walk the dog. Sometimes just once and sometimes every day for a week.

A: Okay, okay but what does it pay?

B: It pays 6 euros for half an hour. 

A: So if you walk 4 dogs at the same time ..... you get rich :) :)

B: No, sorry buddy, that's not the way it works. You can only walk one dog, or two if they have 2 dogs. But then you earn about 8 euros for half an hour.

A: Oh, that's a pity. But I have one more question.

B: And that is?

A: How can you get into the house to pick up the dog?

B: THere is a special system for this. Some kind of post box with a code on it and the owner apps you the code when you are there. 

A: But if someone sees the code he could break in!

B: No, the code only works once. When you come back to the house you get a new code. And so on.

A: But how do you know where to walk?

B: The dog owner sends me the ususal route that he walks with his dog, so I can also walk that route to keep the dog to his usual pattern and not upset him.

A: Wow, they really thought of everything, didn't they?

B: Yes, there are a lot of smart people in the world.
