Although never actually on the lab bench, coffee makers have had a prominent place in every laboratory I have worked in. It is because of my laboratory coffee experiences that I am able to drink coffee at any temperature and at any time of the day. The credit for my preference for really strong coffee (with cream, I confess) goes to two Russian labmates who insisted on making the coffee every morning and went through two bags of beans a week (we had a very wide awake lab).
In all the labs, keeping track of whose turn it was to buy the coffee supplies was just as important as keeping track of whose turn it was to defrost the freezers. I am sorry to say we never thought of a log book because that might have saved me some frantic early morning trips to the store.
Does your lab have coffee rules or traditions? I’d love to hear what they are.
