"It's done"

It's done

Then you open production to check it.

Oh, I just didn't deployed

After 20 min:

It's done

You open production again.

I didn't tested, I will fix this

After 1 hour

It's done

You check production...

I planned to make this X function work a bit later

After 2 hours

It's done

Production...

It shouldn't happened

Next day

It's done

You open <s>Facebook</s>, I mean production

It worked yesterday when I left

After 4 hours

It's done

Looks like it finally works for you and you tell customer to check

It's a problem with his PC

Next day

It's done

Customer says: "We actually don't need this anymore"

I'm done

That's easy / No problem

Because it usually is not and has lots of hidden dangers >.>

"It will take 3 days".

But we believe it ourselves, so it's okay... Right?
