When my dad closed his gas station in 73 gas was 54.9 for full service which included checking your battery and your oil and wiping your windows-- 49.9 for mini service which was only pumping your gas for you.
Mini service was the first thing the industry tried to get more customers before self service was introduced a few years later.
When my DH and I had our 2 gas stations in 1975 cigarettes were 50 cents a pack.
Do you remember green stamps and gold regal stamps? We gave them out at my dad's service station. I remember my grandma saving them for my cousin and I to lick and put into the books so they could be redeemed for merchandise. Toasters bookshelves lamps etc.
