Cor call yourself the artisan window cleaner go round Notting hill on that you’d get £25 per window ?Those Lyons and Dairy Maid ice cream vendors. Those were the good old days.
There was a lady cleaner up your way who had a bicycle with a purpose built trailer. She managed with a small tank, a DI vessel and her necessary equipment. Sometimes had her young kiddy on board. She was certainly an inspiration for all of us. Thankfully, she later got herself a van setup. We haven't heard from her for a long time now.
