Take Up Thy Table???

It happened again. We went to Quizno's for lunch. Since both the tables and chairs in that place are a bit fragile, we thought it best for Don to stay in his powerchair while we ate. As he was trying to get closer to the table, he somehow hit the "forward" button and went ramming into the table, shoving it across the floor! I was standing in line, waiting to pay, and I absolutely lost it. It tickles me to death when the chair seems to have a mind of its own. Kind of like Herbie - possessed!
