I think that this is another example of the police going over the top regarding minor issues. As PC767 points out any offence wouldn't have been committed untill they reported for duty. Surely it's possible to have a couple of drinks the night before and still be under the limit the next day. What are the regulations/guidelines for cabin crew alcohol consumption in the period prior to commencing a shift? I once had an anomymous do-gooder call my base to say that I'd been drinking vat 19 from a bottle in the boot of my taxi, it was iron brew! (Scottish soft drink, the same colour as vat 19)
