Are you telling me that drug dealers don’t ring each other up on their landlines and say “hello. my good fellow. Coukd you sell me a kilogram of your finest Bolivian cocaine please. I will pay you £50,000 of your English pounds. I suggest we meet at 1245 tomorrow (Thursday) in the car park of the Droitwich Sainsbury’s. My man will be driving a black BMW 5 series registration number DrU6 B0Y. Would you be so kind as not to attempt a offence of robbery against my associates and myself as we will be carrying two of Messrs Glock’ s most efficient handguns and we could all get dreadfully discombobulated. I look forward to doing business again with you in the future.”
