Did you get it right?
This old diner kitchen includes two objects that do not belong.

The Answer
The mistakes are the disposable plastic takeout lid and the digital kitchen timer.
Here is why
- Look around the counter and griddle area.
- Find the plastic takeout lid.
- Find the digital kitchen timer.
- Both are modern objects.
Why people miss it
Diner counters are busy, so small modern items can look like normal kitchen clutter.
Did this one fool you at first glance?
