Me - "Talks to client about his deliverable"

Him - So when can we show a demo?

Me - On thursday we could show a totally working deliverable.

Him - "Really on thursday? i was hoping to get it done for tomorrow"

My mind - *Dude. do you even know how much time does it takes to finish the latest changes you just asked me today? i mean probably we could get it done if you weren't so cheap at the proposal, you know, when I told you we would take longer if i dropped the price. And I could have a couple more devs working here so we could had the finish product a week ago, and still we are on time... so WTH dude *

Me - No, sorry I wouldn't dare to show you a half baked demo. But ill try my best to show you before that day.
