1, Introduce yourself, say "hello" – give people a few seconds to recognize you and pay attention. When you are out on the sidewalk, it may take someone a couple seconds to figure out who is talking and where to look.

2. Repeat what a heckler says on the mic—even though it may be an insult. Many people probably didn't hear the heckler, since he doesn't have a mic and you do. You want people to know what "heckle" you are responding to.

3. Do NOT let a stranger talk on the mic. Even if it makes it more difficult or makes you seem less congenial, don't do it. If someone wants to talk on the mic, they are likely drunk and you don't know what that person is going to say.

4. When using a handheld mic, point the mic towards your mouth and keep it pointed towards your mouth, even when you turn your head. The mic is like an arrow pointing toward your mouth, so people know where to look. Get familiar with using a mic and adjusting the height of a mic stand. Also, it's counter-intuitive, but covering the mic with your hand WILL cause very annoying feedback.

5. Don't try to talk over people who are laughing or cheering. Don't try to talk over traffic horns, sirens, etc. Just wait a few seconds and don't stress about it. It might be a good time to take a drink of water. (But Do talk over people who are attempting to interfere with your presentation.)
