Starbucks Observation No. 1

Is it REALLY that hard, people, to say "excuse me" when reaching across to grab your sugar/milk/stirrer at the Starbucks condiments bar?! I love how the same people that will wait long enough for the "barista" to get their "double/double, skinny, mocha, half-caf, more-wet-than-dry" drink perfect can't extend simple, common courtesy when dumping, like, 5 Equals in it.
