When I first went window cleaning an old guy took me out to teach me the ropes, I turned up in t shirt and jeans, he made me sit in the car and watch and said next time I can wear casual work cloths, but a shirt and tie was casual to him

Really lovely person, Bless him, I learnt with shammy leathers his still alive he stopped window cleaning when he was in his 80s I think his 97/ 98 still drives all is facilities
Thank goodness wfp or maybe not my waistlines never thanked me
