Mrs Smith calls some geezer about window cleaning. Asks, can you clean my windows, inside and out, I've got visitors coming, and want everything tip top please?
What do you tell her?
1 Yes, no problem, when do you need them done.
2 Yes, we can do the outsides, but you'll need to get a window cleaner to do insides.
3 Nahh, can't be bothered, I'm a big number on some forum, and I won't get out the bath for a wee for less than a monkey, so sorry missus, you'll have to call some minion to do crappy little jobs like yours. I'm far too busy lookin at myself in the mirror and spouting crap on CIU to bother learnin the basics of my trade. Anyway, I'm scared of heights above 5 feet, and have very little hand-eye co-ordination.
Choose any of the above. I promise to look later.
