Feel free to post, it's just not directly relevant to the question being discussed. It's a valid reason to offer an NHS discount but shouldn't be confused with the question of whether it's "harsh" for someone to decide not to offer an NHS discount. More importantly, it's clear from
@Mister B 's post that he does "get the whole thing" but chooses to place his philanthropic efforts elsewhere. An NHS discount does not make sense for every business so I'm not sure how you can possibly come to the conclusion that offering an NHS discount means a possible 1.2m extra customers for someone else's business? No doubt Mister B knows his own business better than you do. If Mister B is selling helicopters does an NHS discount mean 1.2 million extra customers?
