At any networking event there are people that you want to avoid because they cling to you, and prevent you from meeting new people. Usually an effective technique is excusing oneself to refill your drink or using the restroom. However, recently I was resought out after politely excusing myself. "What was i to do now?" I had gone to the restroom and I had a full plate of food. The solution, I handed them my business cards and told them to call me.
This was the perfect solution. By handing them my business card I was able to walk away and continue to network with other people. Most likely the person will never call me, because 99% of the time, people NEVER CALL. If he does call then he will probably be a lead and not a clinger. While I needed to continue to network, I can take the time in a one-to-one meeting if he is interested enough to continue the call.
