Well because I know it can work, it flows. To be fair I understand where you all are coming from, as you cannot visualize the characters like I can. The scenes I put on here are the ones I wanted feedback on as I am not too sure, but I still think they work.
Steve: middle aged, overweight, short, has an 80's moustache and talks like he is a man's man, hates anything that isn't english. a stereotypical tradesman.
Scott: A young apprentice, who see's the reality of working in the trade, and has dreams and aspirations bigger than being just a plumber. He is university educated.
Basically it is a battle between the two, constantly, Steve is not PC, Scott realises this, and does his best to help the situation when working in people's houses and work.
These two are not the only characters in the sitcom, and is not like 'Empty'.
