Stop Signs in Wal*Mart

Oh my goodness, there needs to be stop signs in Wal*Mart! Yesterday I nearly got plowed into three different times. I was walking down the main isle and had the right of way, when others came speeding out of side isles without looking! Now, I'm not perfect, there have been times that I haven't stopped quite soon enough at the end of an isle and nearly hit someone too. But I always stop and say excuse me and let them past. These people came within inches of ramming my cart that had four children in it and didn't even give me a second look! Maybe we need to have a class that you have to take in high school before you enter the real world called, "How to be a polite shopper" or maybe "How to Drive a cart in Wal*Mart"!!!!
