Getting paid

Getting paid is brilliant, isn't it?
You do a bit of work that you're good at, and then someone pays you for it.
It seems reasonable.
It happened to me the other day.
This guy asked me to paint a picture for him. I painted the picture. I phoned him up and said, "I've finished that picture you asked me to paint."
He came round and said, "That looks great." And he paid me, and took the picture away.
Let's look again at the important part of those last few sentences.
He paid me.
Large corporations unfortunately, don't seem to want to work this way.
You secure a contract with them and submit an invoice.
About two months later you start to think, I wonder when they're going to pay me?
So you phone them up, and nobody seems to know quite what is going on.
So you wait another couple of months and then you phone them again, a little bit more vehemently this time. "Look, it's been four effing months now. Where's my effing money?"
About two months later you get a cheque.
