Do you drink 'n' dial?

Have you seen "Sideways"? A funny, smart movie, though the ending is pretty cheesy because we've heard Virginia Madsen's voicemail message, so we kind of KNOW she and Miles are going to get it together. I love the wine snobbery aspect of it, that is so American: "So, when did you get into wine," "Seriously, about seven years ago," "Seven years, right, and what was the bottle that did it?" - I mean, I got "into" wine through Sainsbury's and have pretty much stayed at that level, thank you very much. And I know nothing about grapes, actually, that should be "knew nothing" because thanks to that movie, I now know that pinot noir grapes are very difficult to grow, thin-skinned etc., as opposed to cabernet grapes, which will grow anywhere etc. etc. omigod, that's enough. Keep it simple: red or white, fizzy or still. I also like the concept of drink 'n' dial, but - and this might just be me - I've NEVER got drunk and made a phonecall I shouldn't have, basically because I could never remember anyone's number and anyway, I'm a "happy drunk." Am I alone in this? Could it be simply a plot device used by filmmakers? I need to know.
