When I was growing up, gas was 70 cents a gallon and when you went to get gas, a young person who was apprenticing at the service center attached to most every gas station would come out, pump your gas, check your tires and fluids, wipers etc. That young person was apprenticing under an experienced mechanic and learning valuable skills.
Those days are gone. Now gas is $4.00 and you pump it yourself. Service? Forget it, you will be lucky if the clerk speaks English. The minimum wage, labor regulations, and government regulations have brought such apprenticeships to a screeching halt.
