One great regret of my life is that I have never learned Welsh, but then I live in a part of the UK where two other minority languages are commonly spoken (Doric in the North East and Scots Gaelic in the West and Western Isles) Not to mention the hybrid Norse/Scots language they still speak in the Orkneys and Shetland Islands.
It can be an advantage when travelling in the smaller nations to be able to ask a shopkeeper in Welsh, Gaelic, Doric etc for a pint of milk.
fortunately, however, as pharmacists have to study in big cities like Glasgow, even those limited to English or French or German or Spanish ... could usually find someone who will understand that they need some Hypermelamose, or contact lens cleaning fluid
