Inciting or suggesting violence on someone for your loss of a few quid is not only sad, it is petty and has no legal justification.
Very recently a crook of a customer of mine was bulshitting me and not paying three outstanding invoices, I paid him a visit roughed him up verbally a bit, suggested what may happen if he didn’t start paying, two hours later the first invoice wa ;s paid by bank transfer, unfortunately the remaining debts have gone the legal route, I’ll wager we won’t see the money.
Basically what I’m trying to say is go smack him on the eye and get your money back. ; )
