This a bit of a quandry then.
The people on the top floors employed me as their old cleaner, sensibly in my opinion wont use ladders to do these flats anymore. These Flats back onto a river, witha steep bank,which no lie is about 10ft from the buildings.
The people downstairs have their own cleaner, so they aren't my custies, and I dont even wont to try and take the other guys business, so what can I do, but offer to blade their windows off for free. This is showing them both consideration and respect. If they refuse this apart from dropping my jobs, which im not gonna do, theres not much I can do to solve the problem.
