I'm frankly impressed the cozzers didn't trouser the lot themselves. "Ahem. Thanks for handing this in, we'll see it gets returned to it's...cough...rightful owners."
I would have pocketed it, any **** who is stupid enough to be waltzing around with £2k in their pocket can afford to lose it.
If I saw some granny drop it I'd without doubt run after her and give it back - but if I found it anonymously I'd just assume it was Venom's coke dealer.
Oh, that was the very skim of the surface of pedantry. If the person was moving to anything other than a three bar beat, your "waltzing" statement was miles off the mark.
I have no idea what point you are trying (and failing) to make, and even less interest in finding out what it is. But you crack on and maybe Toby will like that too
