If you want to order Orange Juice., please don't ask what we have.

I'm confused.  If you would like a glass of orange juice, why don't you just say "Can I have a glass of orange juice?"  It's 105 degrees out and a lady flags me down.  I'm dripping sweat from my brows and she asks, "what do you have" which I reply with "what are you looking for".  So she says it louder, "WHAT DO YOU HAVE".  I say we have a full bar, we have frozen drinks, mixed drinks, beer, wine, soda, coffee, iced tea, and juice.  Her next question?  "What kind of juice"..  Okay...."orange juice, pineapple juice, cranberry juice, grapefruit juice".  And she says "Give me an orange juice".  Seriously lady?  I almost just passed out from heat stroke while explaining to you for the last 5 minutes what kind of drinks we have AT THE BAR BY THE POOL IN LAS VEGAS and you want me to bring you a freakin' OJ!?  I bet when I get back you won't be able to read the tip line either....
