I Was Today Years Old When I Learned This

I was today years old when I learned this. I read this sign at a gas station and legit I realized I was clueless. Naive me thought I was doing a good thing showing my 13 year old how to pump gas for his momma. Anyone else think like me?

Come to find out it is actually frowned upon and not a good thing. A person must be of 'licensed age' to pump gas just fyi. Next time you are trying to show little man or a little lady how to pump gas at an early age, keep this in mind.
