As I've often posted; I'm not much of a drinker but in the past I'd sometimes get a strong mixed-drink like a Long-Island to get a buzz; being a non-drinker often times one LI was enough for a buzz.
But I noticed that LIs in the upscale clubs would usually give me a buzz but at the dives one LI had no effect leading me to assume the dive LI either had very little or just very poor quality alcohol.
Have you drinkers noticed any trend in upscale vs dive alcohol in terms of quality – or is it your experience that it's just club-dependent and independent of it being upscale or dive.


Even poor quality alcohol should get you drunk. Usually lower quality booze means you'll feel it more the next day, but it should still easily do the trick. So if you're not feeling a buzz off one LIT, odds are they're going heavy on the cola and light on the booze. Or they've done the old bar trick where they've watered down the booze in the bottle (or an employee has done that to hide the fact they've been stealing booze).
A lot of bars will also pour the cheapest booze possible into top shelf bottles.
A lot of bartenders HATE making LIT. There's way more labor involved in them and usually people tip the same dollar as they do for a beer or jack and coke. And it's notorious as a drink for people who want to get drunk for relatively cheap.
All that said, I'm a cheapass who will bring my own flask either in my car or into the club.
