Fixed Price?

Pet hate. 'Fixed Price' menus that AREN'T actually the set cost deals they purport to being. Today, while scoping some restos in Glasgow for an upcoming event, we witnessed countless gastronomic outposts whose 'Prix Fixe' were littered with the word 'Supplement'. One menu in particular, had all supplements been chosen, would have witnessed a price jump from fifteen pounds to nearly thirty. Come on! The word 'supplement', as we see it certainly, is not welcome on a fixed price menu. In that context it drives us insane. If there are supplements it is NOT technically a 'Fixed Price' menu. 
Note - there will be a five 'Bitcoin' supplement for anyone who disagrees with this epistle. Please and thank you. Colin and Justin xx
