Being a dj you are the center of attention in the club lets just call it “famous” for a lack of better words, alot of people dont know how to act around famous people and since you the dj made such a deep impression on them they want to do something to stand out and share in your fame and let you remember them too unfortunately it mostly means being annoying, having alot of cool fans is really encouraging but for the people going out of there way to annoy you try to put up a physical barrier like put all your bags chairs whatever at the entrance of the dj booth to discourage people from getting to close, also if someone is bothering too much its good to have a friend nearby to play bad cop and they can be the one to tell them to go buzz off and u can just concentrate on being the nice guy dj without having offended anyone, some cool fans its not annoying but just distracting when alot of people come and want to ask the name of the song or just say they like your music ,for these cool fans I printed a qr code and made it visible so anyone who wants to talk to me can just add me on their phone and after im done ill be glad to chat with them online, Some uncool people bother alot coming in and asking how much does my equipment cost and completely random topics like street directions or even more extreme like this one guy would come and stand next to me and start pulling my hair or another guy come and start dancing on me and almost knock over the dj booth I now put chairs and junk to block these kinds of people from coming close and also have my friend who will not very politely tell them to get lost ,you never know who those annoying people are maybe they are the club owners friend or someone with influence maybe they might later become one of your super cool supporters that you count on ,so its a very delicate balance to try to not offend these people that are annoying you
