If I'm holding an effort, ignore them. If I'm not, look around say hi, tell them what I'm doing today and ask what they are. Then decide to swap turns ride on front, or drop them. If nothing else it gives you a chance to see how Freddish they are.
For me the annoying ones are when I'm trying to hold an effort, you pass someone, they sit on and then pass you trying to help out. What do people do in this situation. Remembering you are trying to hold constant Watts. Dropping back is pointless, as doubtless this guy is riding slower than you. Accelerating is pointless as riding away will push you over the limit you were riding at. I've again resorted to talking, "I'm trying to do this...sit on, or ride away please" any better answers.
