Yes! Brilliant rant twt - love it! However..........
a) If you want more business, especially in more "select" or commercial (profitable) areas a uniform is good because business and professional people generally prefer a smart look to the raggedy ars*ed, f*g-smoking look.
A uniform need not be expensive. Go to your local workwear supplier (Aarco for example) and for about £35 you'll get a zip up jacket with chest pockets and trousers with sewn in creases (like van delivery drivers often wear.)
You can wear the top with shorts or the bottom with T shirt when its warm.
And like Tosh says you can wash it with your scrims.
And of course you can choose to wear it only when its useful to do so - "calm down dear" it's only another tool in your toolbox.
B) Professional window cleaning mag/leaded lights
They're doing a good job - but the leaded light cleaning article made me smile too! I think it was Graham who said the essence of "Only worry if you're licking them clean."
I use a trolley and a J reg Honda Estate and I'm no example of sartorial elegence either! (But the uniform idea is a good one and I get more "asks" on posh domestics since I bought mine)
c) Of course Tosh's uniform should have 3 stripes and a crown on the upper sleeve.
