Mistaken Identity

On holiday in Orkney in 2017 Visited a historical site “Four adults please” Got three adults and a concession Concession? What???!!! Who’s the concession? There are no students Or over 60s in our party It was a case of mistaken identity They thought I was too young to be an adult They didn’t think to ask my age Or for student ID I was twenty three years old With no student ID I was unemployed Nothing to say unemployed are concessions We queried it They wouldn’t change it This mistake meant that I couldn’t get my money’s worth It was a silly mistake No ID means no concessions They should have changed it So I could get my money’s worth Since then I have wondered Why anyone would sell A concession ticket To a non concession 26/07/21
