How sound this is, I'm not sure, because some habits seem as inconsequential as a statement regarding time and vice. It makes one wonder how long it takes to believe a statement to be true. Possibly as long as a *** of coffee to be brewed.
Surely the amount of time will vary by the weight of the statement. But even a measurement is prone to be thrown off by unforeseen additions. Eight cups of water, and four scoops of grinds, you're bound to have a little too much or a little less than expected. It becomes harder to tell when dealing with a slow drip. Brewing coffee may be completely divisible when dealing with a recipe, but hardly unequivocal when the time comes to measure up. This follows suit with patrons and their proclivity.
Only in fiction is the coffee shop patron enigmatic. Only in fiction can the patron enjoy a cigarette indoors.
Men and women wake and head to their cubicles, coffee in hand, five days a week. By the third day a habit has formed, and maybe that is why acceptance is had midweek and why the first day of the nine-to-five seems so everlasting, if not inscrutable.
