Wow! Other than some rare post-hallowe'en egg I've not had any of that stuff lads! And. frankly you'd have to pay me mega bucks to do it!
As I said to one of my ex-customers after they had a £12,000 extension added and the builders left sealant and rendering stains on the glass and frames.
(After a discussion where the householder thought an extra fiver was enough to pay and asserted that "the window cleaner should clean off anything that was on the windows since the previous visit!")
"If you think I'm getting that lot off for an extra five quid when you've just stumped up 12 grand for the laziest builders in town you must have rocks in your head!"
