Okay. A) why would you need to buy alcohol in Vegas? Go to the damn casino.
B) big liquor selection, but not as good as Bevmo. C) Korean favoritism is ridiculous. I mean they sold these kids liquor without even checking ID which is sorta sketchy and seems unsafe. D) Lee has a thick-accent, and is sort of rude when you ask him to locate something for you.
Overall, save your money and drink in the casino (or Bevmo). And tip the paid-to-be friendly/attractive waitresses. Better than dealing with a middle-aged Korean asshole.
