Hawarden and Humberside aren't pleasant, but they pale in comparison with Sumburgh (where there's open-but-undeclared warfare between 'security' and the pilots of one mainly-Scots airline) or, worse still, Benbecula. Much of the stuff you've been reading in CHIRP over the last year or 2 refers to aircrew experiences in those 2 places. Unutterably dreadful, both.
