When I first started window cleaning I use to collect towards the end of the week. Thank goodness for online payments, etc. Collecting is a waste of time and petrol. Thank goodness I stopped collecting years ago. Still see a few trad w/c's out collecting Friday evenings, such a tedious job that isn't necessary anymore unless it the fAgs & booze brigade with cash in hand.
I'm trad, don't smoke, very rarely drink, and declare all my income.
I also collect on a Friday evening, and enjoy doing it as it keeps me in personal contact with my customers, something that seems to be dying out with many of us who wouldn't recognize our customers if we met them in the street! 😊
