This one has risen to the top. It’s the customer at Starbucks who gets his/her drink and stands in the middle of the condiment counter, blocking it, and then slowly and deliberately pours some milk in, swirls it, tastes it, pours a touch more in, swirls it, tastes it, perhaps considering the fullness of its bouquet, and then does the same with a sweetner. Then, after a final swirl, tastes it once again, to make sure the final mixture is just as they like it. It can go on for minutes, In the meantime all I want is a bag of sweetner and a stir, but they stand in a way that you would have to reach in front of them to get it. I suspect it’s on purpose: for a few seconds, the world revolves around their tastes.
