Greetings to all;
Yes, it really works. A shipmate aboard an aircraft carrier on Yankee station (Nam sense talk) did that. He just carried an empty folder and was dressed in his class A's. Was never bothered. Easy and useful technique for all you Wally wannabes. A grand day to all.
While I must admire Wally's technique in avoiding interaction and work while at the same time broadcasting "busy", we haven't seen his A-game yet. Wally should be fully capable of getting *others* to do the moving while he sits back and doesn't spill his coffee.
