This photo of tables and chairs, besides being about a repeating pattern, has an additional significance to me.
I used to work at a restaurant that used this same model of tables and chairs. The tables are solid, though top heavy; but, the chairs have a tendency to buckle under very heavy people. If you're up over 200 pounds, you do not want to scoot backward or forward. You should lift it and place it where you will sit, and then gingerly sit down.
Rather than slide across the floor under the guidance of a heavy person, the leading leg will tend to catch on something and then bend. Anybody that heavy will not hit the floor gracefully. It's quite a scene.
