Check out animal behavior: Do they eat like Canada Geese, mice, squirrels, sparrows, lions, birds of prey . . . or?
Watch their gestures:
Hand waves from elbows on table
Palms up side wavers
What they do with their plates and utensils:
Spooners versus fork users
Knife stabs food item then goes straight to mouth.
Food arrangers: move items around the plate for correct positions.
Napkin usage: folders, ballers, scrunchers
Pushers away and then up to mouth
Dainties and little finger wavers
Food sharers, sneakers and stealers
Side to side wags
Cocked one way, then another
Head lean on hand or arm
Lean on another's shoulder
