Yeah those aren't great things. It's so easy to premix spices in a prep bowl and to toss a towel over your shoulder while you cook. I use a lot of wooden cutting boards, I prefer them. Except for poultry. I have 2 specific bird prep boards that are thick plastic and are only used to prep poultry on. I don't want that x-contamination on my butcher block cutting surfaces. I'm not a germophobe, but I don't like the meat juices all over my hands when I'm cooking so I wash fairly frequently during the prep process. I think it takes less effort to pre-prep and have everything you need ready to go than it takes grabbing things as you go along. You are also limiting the area of potential carnage in your kitchen to clean up after.Sometimes in general. I've seen plenty of guys who use wooden cutting boards when prepping meat, then use their unwashed hands to season the meat and pull spices from the jars with their fingers. There's also drying hands on the backside of their pants, drying them on your shirt isn't sanitary either, but I'd rather not see someone rub their butt after washing their hands.

Am I an exception? Maybe. But I did food service jobs when I was younger and I cook with a friend who is a trained chef, and I pick up cues from him.
