Not disputing what you say SAS.
What I find difficult to understand is how someone allows a few minor inconveniences to build up to the extent it stops them visiting Oban. The reality is that during a visit most of what you mention is not experienced. Sure the displaced threshold has you scratching your head, but whether the welcome when you have landed, or having to request permission to start causes a frown, anger, or simply a smile is up to the individual.
I doubt it stops you from visiting.
