walmart

I was at walmart yesterday standing in line at a "express" checkout. I was in line with about 4 other people. I stood there and took a quick count. Of 28 checkout lines, 6 were open. These each had something like 2-4 people in line. what the hell is the point of having 28 checkouts if less than 1/4 of them are going to be used? I hate walmart enough as it is without spending half my life standing in line there
