No. Cos i added a rolled eyes to the mbs question?
It's like me asking you if you can clean a window, Or know how to turn a computer on.
I think people (granted probably me) are missing the point about the 20% discount claim.
If it's implemented it is undercutting. I question how many times it can be proved what the previous window cleaner charged. Only because i can't see how most can.
So while the claim of 20% cheaper than previous is out of order. I'm reading it as a claim that 99% of domestics can't prove. So the claim has little substance.
It's just my opinion though.
