If an IT person meets you to help you get into their LAN or internet or ... Be kind. If an AV person meets you to help you with a microphone or getting your laptop projected to the big screen -- Listen to them. Every event venue has its own personality. Not listening to the "help" may mean you didn't hear them tell you were the mute button was on your mic. If you have never been to the town before and someone is picking you up at the airport or hotel, you may find out where the best place to eat is or what not to say to the new sponsor who just finished chemo and has a wig that doesn't look quite right so be careful what you say about her hair (true story).

You may make a connection with the greater audience, but how you treat those who work with you as you are presenting can also make an important impression. These talented individuals can also say things about you after you are gone. They speak and deal with important people. They dealt with you didn't they?
