re the line of mine you repeated above- there is NO PLACE where that insensitive approach should be inflicted on innocent people who just want a drink & chat- a public bar is no place for manuscripts.
An acquaintance of mine once spent years with an old Sussex musician & learned all his tunes, note for note. He became a fine player of the notes, but an older & knowledgeable observer remarked- 'he's learned all the tunes but that's all he's learned' no communication skills
I haven't been to Edinburgh lately & no doubt it's changed since the days of Paddy Bort (RIP) as well!
