Many years ago I rented a two-story former store in Ireland. I worked there all day for long hours. Half the time I took on graphic design and web projects on the upper floor and the other half I worked as a physiotherapist on the lower floor.
For reasons I can’t explain, my design clients always paid their invoices on time. Always. But the clients I saw as a physiotherapist were nearly always late in paying or quite often, refused to pay their invoices at all.
I had one client who had suffered from a chronic condition for many years. I treated him successfully and finally I sent him an invoice.
He sent me a letter in response:
Client: Thank you so much for your intervention. My life has completely changed thanks to you. I’m back at work, playing golf again and just feel so much better. Thank you for your help. However, I will not be paying this bill. Sorry.
