Two Mistakes in This 1960s Cafeteria Return Line

Did you get it right?

This school cafeteria return line shows stacked trays, milk cartons, napkins, a silverware bin, tiled wall, lunchroom clock, and students returning trays. Two small details are too modern.

The Answer

The correct answer is: The two mistakes are the compostable tray emboss mark and the peel-back yogurt lid tab shape..

Here is why

1. The trays, milk cartons, napkins, clock, and tiled return line fit the old cafeteria scene.
2. Look closely at the tray corner and the foil/yogurt-lid detail.
3. A compostable emboss mark and peel-back lid tab are newer packaging and school-lunch clues.

Why people miss it

A cafeteria return line is already full of trays, wrappers, cartons, and small scraps, so modern packaging details are easy to overlook.
