Do you really believe it was free?
Do you want them to inflate the price to pay for trinkets?
I like the humiliation factor.
Shiny things are better than smoke and mirrors....
Back then there was a gas station on every corner, and they fought for customers. I remember making(begging) my Dad fill up at a station he didn’t usually patronize so I could get a free yo-yo. The station he usually used gave away glassware.
Most people’s entire knowledge of the oil business is how much a tank of gas costs, which is understandable, but results in Bill O’Reilly type ignorance.
