To me, this sounds like the following analogy....
Pietro Pirelli has a large amount of money saved in a deposit box in the Barcelona bank. However, Pietro cannot be bothered to wait for the bank to open, so instead asks everyone if they would be willing to go and withdraw his money for him. Manfred Mercedes agrees, but then realises he's going to have to break into the bank to get the money. However, rationalising that it was Pietro's money, and Manfred wasn't getting anything else out of the bank robbery, he agrees to go along with it! However, Ruttger Red Bull hears that Pietro has now got his money, and that Manfred had done all the work of breaking in! Ruttger argued that it was impossible to pros that Manfred hadn't benefited from the raid himself- and should be punished as a bank robber......
