One thing I'd like to mention, and I'm sort of embarrassed to do so, but be a Rachael Ray. Geeze, I just noticed Shroom said that too. LOL. I'm not all the keen on her show, but she commands being watched if you happen to see her.
Out of curiosity, when Food Network was doing their "Next Chef" programs, I watched one episode when Rachael Ray was talking to the contestants about 'working the audience.' You know food demo is what she did before becoming one of Food Network's most watched programs. Not bad, eh?
I used to do an omelette station when I worked along the St. Lawrence River in Upstate NY during Sunday brunches. I am NOT a people person, but I sure managed to have fun. Even though you'll be demo'ing the same thing over and over, vary your patter (speaking) so that it doesn't sound like a prerecorded message.
If insurance concerns allows, select a volunteer to help with basic things.
Ciao,
