Do you realise how much time we invested in. . ..?

Imagine you are at the bar of your local pub. You would like to order some food & drinks.
You catch the eye of the barman who nods to indicate he has seen you and then stands still, as if deep in thought.
The barman looks at the floor, then looks at you, then focuses his attention on the glasses, and bottles behind the bar.
After about 10 minutes of this he slowly walks over to you.
I expect you are pretty frustrated by now.
Slowly and carefully the barman pulls out a pad and pencil from under the bar. He asks you what you would like, you ask for 2 pies & 2 pints of your favorite, he slowly and carefully writes this down. The barman then turns the pad around and asks you to check your order. You review it, it appears correct and you tell him it's good. He then asks you to sign it, in order to confirm you agree.
Astonished, you sign it.
The barman asks you to take a seat, "your food & drinks will be with you within 2 hours" he informs you.
what?
"and that will be $6,500 please"
" WHAT?!?!" you scream out loud
"well look how much time I am putting into this, and I spent 3 years at university studying bar service"

It seems strange to me that people believe that because they invested more time into a project it is worth more. Surely it is more valuable to get great results sooner?
The most value should be given to results that are delivered fast and provide what is needed.
