Are you one of these people? I'm standing in line behind you with 7 items -- simple to scan, simple to pay for with my Visa checkcard and simple to move on through so the guy or girl behind me can get on with their life, too. YOU: You are the person in front of me with $18.07 in groceries. You are the one that pulls out a crumpled up checkbook and proceeds to write a check. After spending 2 minutes of my life and everyone behind me, you screw up and proceed to rip up your check and start anew. You balance the back of your checkbook before handing the cashier your check. Now, enter a new revolution called the "check card." You swipe this magical thing through this magical slit and instantly are on your way. Don't worry about security, Visa and your bank have you covered if something goes wrong. YOU -- GET RID OF THE CHECKBOOK AT THE GROCERY STORE!
