"A Qantas flight attendant who got blind drunk on peach martinis in a New York bar during a layover has lost his appeal to win his job back."

"Luke Urso, 24, claims he drank just 'two peach martinis and three gin and tonics' at the 230 Fifth Rooftop Bar in New York in 2017 but due to the bartenders 'free pouring' the cocktails, he ended up collapsing in the toilet and being rushed to hospital. Mr Urso believed that while he thought he was drinking five drinks, he had really consumed the equivalent to 14 standard drinks - resulting in him unable to work his shift the next day and Qantas having to foot the $20,000 hospital bill.... [The Australian Fair Work] full bench said Mr Urso's evidence could 'simply not be accepted' saying he 'could not seriously have thought that a drink in the nature of a peach martini would only contain one standard nip of alcohol,' it said. 'The evidence tends to suggest that he had significantly more than five drinks, in which case 'free pouring' loses whatever capacity it had to exonerate him,' it said."

Are you familiar with "nip" as a specific small amount (like a "shot")? I see there's an old word "nipperkin":

Nipperkin was still around as the nineteenth century turned into the twentieth, but lasted little longer.... There are a number of references to it in books of the period, as in The Dynasts by Thomas Hardy, published 1904-8 but set at the time of the Napoleonic wars: “I’d sooner have a nipperkin of our own real ‘Bristol milk’ than a mash-tub full of this barbarian wine!” [Bristol milk = sherry.]

Its name is so intimately tied to English and Scottish rural and domestic life that it comes as a mild shock to learn that the word is probably Dutch in origin and is related to the German and Dutch verbs nippen, to sip.

We still sometimes speak of taking a nip of spirits, often notionally for medicinal purposes, as a character did in The First Men in the Moon by H G Wells: “He recommended a nip of brandy, and set me the example, and presently I felt better.” Nip here is an abbreviation of nipperkin, in the looser sense of any small quantity. However, nip has some more specific senses: it’s a legal measure in Australia and New Zealand, of size 30ml; in the USA in particular it’s usually one-third of a local pint, a bottle size for high-alcohol beers like barley wine.

And what is "free pouring"? Is it wild or careless oversizing of portions? That's not what I'm seeing:
