holes in bread slices, or as i like to call them : gloryholes, are nothing to be worried about. if youre making a deli meat sandwich, just dont put the mustard on the hole side, stick meats and other solids that wont go through. if youre makin a pb&j, put the peanut butter on the hole side, depending on how oily ur pb is, it shouldnt fall or get squeezed through the whole as easily as one would think. just learn how to hold that sandwich and there will be no mess. happy eating, if that post didnt suffice then please enjoy this picture of me drinking McBeer in brussels.
