If you think
I'm being unreasonable then go into a corner shop and see the reaction
you get if you try and buy a mars bar with a 50 quid note.

Isn't there an actual law that allows retailers the ability to refuse
payment if offered in too high a denomination?

They don't have to give change, and most of the time can refuse to do
the transaction if sensible payment isn't offered. It gets a bit blurred
in the public imagination when the retailer is a "public service" (sic).
