I don't always eat pizza when I shoot pool, but when I do, it's green olives, black olives, onions and mushrooms. Make the beer taste even better :thumbup:
I hear that pizza grease is the secret to a smooth, chalk free shaft.
(Disclaimer: The above secret is unverified hearsay only and I will not be responsible for your greasy, smelly shaft and the creatures that it may attract.)
My favorite pizza is pepperoni and tomatoes on pesto sauce. I don't generally eat while I play though, and on the rare occasion I do it's always something with a fork, like a chicken breast salad or some mac and cheese with bacon and jalapeno.
A pool hall in San Diego had a pizza oven and play all day deal for 10 bucks. You could use the ten bucks on food or drink. I'd get a pizza margherita or shrimp pesto pizza and it was awesome.
You WILL miss shots on purpose when its tasting good though...what's one missed ball when you're up a couple games compared to the pizza getting half warm?
Obviously if you care about getting gunk on the equipment, you need either to use a knife and fork or wipe off your hands before you go back to the table.
