Anyone else have trouble opening those clear plastic produce bags at the grocery store.. you know the ones that come on those rolls ..the ones that you can never locate when you;ve got a handful of peaches. I watched one guy struggling to try to open one . he was using the rub your fingers together method to try and seperate the sides. the same technique i use then you blow on it to get it to open... is there a better way or were they designed by allen funt
