Sitting in the coffee shop, I sometimes take a break to pay attention to the people waiting for their coffee. Some are jittery, constant movement. Like they’ve already ingested a significant amount of caffeine, buzzy as little kids on a sugar high.

Then we have the impatient customer. Frequently tapping a foot, normally with hands in pockets or arms crossed, they look like they’re sighing over the unfairness of having to wait so darn long for their drink. Many of these will turn to their cell for comfort, chatting, texting, reading stuff, watching videos.

Others waiting for coffee assume a cool Steve McQueen demeanor, leaning back with mild indifference. The coffee will come and nothing they do will hurry it, so why bother? It’s not surprising to see some of them casually check cell phones, oozing as they do.

Fourth are those with the coffee stare. Stiff as a bronze statue, usually with their arms crossed, they posture right up against the counter’s edge, eyes opened wide, unblinking, waiting for their order. As drinks are made, you can almost hear their neurons shouting, “Is that mine? Is that mine?”

Finally, we have the laissez coffee set. Ordering, they find a table or sit until their order is called out.
