Why so expensive?

The Customer:
How much will it cost to perform this work?
The Master:
– $1500
The Customer:
Why so expensive?
The Master:
How much do you think it will cost if you do it yourself?
The Customer:
Maximum of $800. On the other hand, it does not seem to be a difficult job.
The Master:
For $800 I offer you to do it yourself.
The Customer:
But... I can’t!
The Master:
Well well! I will teach you this work for $800 and you will gain the knowledge for the next such event.
The Customer:
This is an interesting proposal. I agree!
The Master:
- So, you need to have with you: welding machine, electric saw, drill, gloves and...
The Customer:
and stop! I don’t have all this equipment and I’m not going to buy it just for this job!
The Master:
In that case, for this work, for $300 I can rent you the tools.
The Customer:
Well well!
The Master:
We have agreed! We are waiting for you on Tuesday to do the work.
The Customer:
and hm. I cannot on Tuesday.
The Master:
Sorry, but I’m only free on Tuesday. All other days are occupied with other orders.
The Customer:
Okay okay! I have to change my plans.
The Master:
“I’ll gather all the necessary materials and you’ll have to load the car on Tuesday at 6 a.m. Please do not be late.
The Customer:
At six in the morning? No is! I am not comfortable at all. You know, I’ll probably still pay you those $1500. After all, I myself understand that I will still not be able to do this work qualitatively and I already understand that it will cost me much more in the end.
