I have never liked the combination of a long flight and lots of booze. A couple of drinks ...yes. Never enough to get drunk. Some people just seem to see heavy drinking as par for the course on flights, train journeys etc.
Surely the airline/train company has a duty to refuse passage to obviously drunk and unruly passengers? Just apply the rule.
Am I a saint? No.....in my rugby playing days alcohol went with the game, but I didn't like being drunk on a long journey so refrained. Drank a few but not too much.A personal choice.
What also annoys me are unruly children allowed to run riot by parents. Often the parents are too "busy" to control them and get bolshy if anyone complains.... a slight drift of thread but similar.
