The person with all the groceries and the person with the child are usually one and the same! They are also the person who can't find the barcode on anything, does something wrong and has to wait for the attendant, changes their mind about several items and just leaves them there taking up space when they leave, takes forever to leave because they lose their keys in their purse and decide that they MUST find them before they pick up their bags and move out of the way...
