Lately we’ve taken to stocking a motley assortment of caffeinated products. You know the kind; you can buy them by the bushel at ThinkGeek. As I write this, we have tins of Bawls Mints, Penguin gum, Think Gum, Jolt Gum–quite a lot of gum, actually–and caffeine chews.
They have small print with notations like 1 cup = 1 chew. I’m not really a caffeine person, having sworn off of pop years ago and never warming up to coffee. I’m in a poor position to know if they really help with productivity, but they do seem to be popular among the tech crowd.
