Yet Another Door Distribution Again. This time we have the wear pattern on the inside of the doors at Potbelly's sandwich shop in Rockville, MD. This is the typical pattern of people holding the door open to enter the shop. Their fingers wrap around the edge of the door. As is usual, more hands seem to have left their entry mark by opening the right-hand door (the left-hand door in this inside image). The most wear is shown at a comfortable height, perhaps shoulder-high or a little lower. There is less wear higher-up and also lower-down where it gets more awkward to hold the door open. There does seem to be a longer lower tail on this bell-shaped pattern of wear suggesting kids have also left their marks.
