Having my wife with me at the self-checkout is aggravating. She wants to help by handing me stuff from the cart but I want to scan stuff by the way I intend to bag it. I don't want the dozen eggs before the 1/2 gallon of milk or the loaf of bread before the cans of beans. I thought I had it fixed until she decided she would help by bagging our groceries. She hasn't grasped the don't pick up or move a scanned item from the table or you get to hear the dreaded "Please place the scanned item in the bagging area." concept. She is nice though and takes good care of the dogs.
