re alcohol service on qantas there are two types of crew. the first is the crew who have been flying 10 years or longer before the requirement to hold a 'responsible service of alcohol' certificate before applying for the job. training also emphasises the 'one drink at a time'. there are different ways of saying "no" to two drinks and a lecture is certainly a waste of everyones' time. crew who have been flying longer than 10 years mostly will provide an extra drink during the first service as, with the reduction in crew numbers, SLF can often be waiting for their first drink for more than an hour after take-off. however even the oldies are loath to give two drinks at a time further into the flight. with regard to the lecture your wife received, i apologise and hope that it is not repeated.
responsible service of alcohol gets discussed occasionally in the galley. some years ago a senior member of crew (30 years flying) was asked what he thought 'responsible service of alcohol' meant. his reply; "don't spill it on the passengers"!
