Are you in?
August 23rd, 12:23pm. It's Wednesday. You're at your usual spot for lunch, "Louie's", a small sandwich shop in the neighborhood. Louie comes by to take your plate away, and leaves your tab. You turn over the tab and there is no bill, only these words "Come back here at sundown, make sure you're not followed." You place a 10 dollar bill on the counter and leave.
