Re. the odd missing bottle of booze:
On the one hand, such pilfering eats into the bottom line and can be conducive to a 'bad attitude' developing - and to strained relations with less larcenous members of the crew.
On the other hand, from a purely selfish male point of view, I must confess to having enjoyed the odd ummmm frolic with said larcenous crew members (their being suitably lubricated with contents of said bottles, following the inevitable room party).
On the gripping hand, schedules these days are sufficiently sadistic that the appetite amongst all concerned for 'frolics' is not what it once was...
