Hi guys,
I've been approached twice now by different window cleaners asking if I can supply them with water, before I've said no as I already supply 2 other cleaners and don't ever want to be short of water for my own work.
The question I want to ask is what you think is a fair amount to charge for water? If you use 50 litres as a guide but obviously they're more likely to take between 4-500.
Thanks on advance
