How an individual copes with alcohol comes down to the individual themselves, not by the generalisation of a group of people be it by race, gender or employment situation.
I'm sure there are plenty of sleezy salespeople who take advantage of the system just as much as your fifo tradie.
Im fighting a lost cause anyways, thanks to the previous governments effective campaign on turning Australia against the mining/fifo industry.
Perhaps the below could be an interesting discussion next time you bump across your Flight attendent friend?

4.4 Mining boom benefits for air services
Between 2004–05 and 2011–12, domestic aviation capacity grew robustly both between the capital cities and to regional Australia.
In Australia, aviation seats (as measured by revenue seats available and passenger movements)
have increased at over 4 per cent per year over the seven-year period to 2011–12.
From 40,429,000 passenger movements to 54,985,000 = 36% increase
I wonder how many extra staff were hired to cope with that increase?
Edit: and just to make it clear; not justifying rude behaviour but the overall stereotype/resentment towards "FIFO" tradies
