I usually concentrate on business at hand and continue to work as if no one is there.After a few minutes they get bored and wonder off.The ones who ask the questions I'll take my headphones off and explain to them I can't hear them and ask them to repeat the question,again they don't like talking to someone who keeps asking them to repeat questions.I'm there not to argue with or entertain people at the park and like to have a good hunt experience.Common sense I don't metal detect near other peoples activities and respect their space also.
