OK, this is a pet peeve of my DF and myself. Just about all of the reasons I have read here are good and make sense. What really irks us is the guy {gal} sitting at the next table at wolfgang Pucks doing BUSINESS stuff. C'mon, how important can you be? Your on vacation, take a break, give your family a break. Business will still be there when you get back.
It's kind of like people with cell phones glued to their ears everywhere they go. At WDW, OK, contact the others in your party and tell them where you want to meet for lunch and stuff. But to walk around and talk about absolutley NOTHING. It kind of reminds me of the young kids smoking because they want to be cool. Sorry, it is no longer "cool" to talk on a cell phone. Everyone and his mother has a cell phone these days, and you are only annoying others around you. Whew.... Every so often I feel the need to rant!
