Do you ever correct people? If ever, do you think it's appropriate? Have you ever received pointers/corrections that you appreciated? If someone comes up to you and delivers bad, unsolicited advice what's the most politic way of handling it?
Most of the time I have my headphones on and simply go from station to station not looking at anyone just staying in the zone and I would probably not notice anyone doing something unless it was pretty crazy and dumb. In these extreme cases I tend to ask the person what the benefit of that exercise is.
Thanks
