The OP did a month's worth of business in 2 days, and the subsequent goodwill generated and publicity gave him a permanent business boost.
His preparation was very well rewarded.

For better or worse, gasoline tends to be break-even for stations - from the operators I've talked to, maybe they make 5 to 10 cents per gallon. They make most of their profit from the shop. A month's worth of gasoline sales might not cover the upkeep and depreciation of the generator.
I'm more curious to know if any other stations installed generators after this experience. I wouldn't be surprised if the answer was "no".
