Two is not better than one

Can you think of a situation that two is worse than one?

After being told that my car had some weird burnt smell, I took my car for oil change this morning. As usual, the job was done in an hour. I was on my way back to work. Before entering the freeway, I noticed that the engine oil light was on. I immediately found my way to the nearest parking lot and parked my car. There was no engine oil left in the engine.

I did several things right at the moment.
1. I called a brother for advice.
2. I called the shop about the situation.
3. I insisted not driving the car back to the shop.
4. I prayed.

The technician from the shop came and he found two oil filter gaskets on the oil filter. It was because the old one was still attached to the engine. Oil was leaking from space between the gaskets. He removed that extra gasket and filled up the engine with oil. My car is on the road again. Hopefully I did not over stress my car.
