Call ahead and order what you want. In our cellular-happy world, this can happen in transit. The idea is that the delivery point is on the path you travel regularly--in the train station near work, a block away or at on the edge of the parking lot. As you're walking that last stretch, don your bib, which carries the number connected with your house account (which has already been debited for today's order). Then look for the person holding up a sign with your number, who will, as you approach, hold your breakfast, lunch, or cup of much-needed coffee at arm's length between light fingers. Whisk away your order as you hurry past, and arrive on time.
