I've had food poisoning before, not the spy movie kind but the under cooked, spoiled, outdated, etc. type. I absolutely will not eat food at a potluck type setting. No baked goods from neighbor, coworker, etc. No drinking out of glasses away from home. Give me a bottle of water and I will check the ring to see if it's been opened,and I will squeeze the bottle to see if there is a pinhole in it. I never complain at a restaurant, and always order sandwiches plain so I can inspect the individual pieces for contaminants.
