I believe you should use a clean serving spoon or fork for pickles, relish, mayonnaise, butter or any other food on the table that is shared. A friend says that's crazy. Her son just grabs pickles with his fork, after he has eaten off it. He uses the knife for peanut butter and licks it and then uses it to get jelly. I feel sick and don't want to use any of the food in his house. Is this dangerous or just pain poor manners? Thanks
