After 12 years, all my customers are pretty good, but I am getting rid of the larger, more awkward ones, as I'm coming up to 60 years old.
Luckily, at my age, something hurts, aches or creaks, so I just text my customers to say that I am cutting down on my workload due to health reasons and would they like my friend Daniel to take over from me.
My window cleaner mate 'Dirty Dan' gets a new customer, I get a drink and it's happy days.
