So how does a pilot of a helicopter cope with an intoxicated gang of revellers.
Alcohol is a great leveller. It doesn't matter how important a passenger thinks he or she is, when they've had one too many they all act like a*******s.
Have done many Epsom, Ascot, Goodwood, Cheltenham etc shuttles in the past and have had many tipsy passengers on board. If they're really too far gone, feeding them coffee and telling them they're going nowhere until they simmer down and sober up usually does the job.
