Cell phone etiquette ????

Are you really that important that you need to be on the phone while you are trying to order and pay for your coffee?? Most likely NOT, so hang it up and and don't be RUDE, that is a person behind that counter and they deserve the respect to take your order all at once not between huh, what, hang on, yes that was a venti, really he said what ? yes non-fat, can you meet me for a drink, yes extra hot. Girl I'm at the Starbucks ya getting a coffee, that is non fat right, yes they are making it right now, uggh I need coffee. Does this sound familiar? Well, I'm here to tell you it's RUDE.
