Agree with much of the above.
We have to use Ryanair a lot because they offer the only flights to family.
On one notable occasion, staff confiscated all food and drink bought by passengers getting onto the flight! They seem to have stopped that now, thank goodness.
We have also managed to arrange the PB thing on most occasions and - I have no idea why - a couple of times, staff let us get on first because we had children and wanted to sit together, even though we didn't have PB. No idea why they did that!
I find the staff are frazzled, hassled but fundamentally OK.
The passengers do seem to have a higher-than-average component of lairiness.
One of the absolute, utter highlights is watching people get fractious over the carry-on size/weight restrictions - which are ruthlessly enforced. I know it makes me a bad, bad person but I always wonder why people try it on. Surely there is no-one who does not know this about Ryanair?
The boarding scramble is genuinely a bit scary. It makes you realise that civilisation is but a thin veneer.
