This comes across as whinging that the course was too difficult. The “designed in a pub” part (and insinuation that Glaswegians are all drunk) could potentially be classed as racist; I doubt it would have been said if the course was set in a different country.
Powless seems to get it - the course required different tactics and a more technical approach; it’s not what others “like” but the course is equally hard on all of them.
