Interesting tidbit about a West Seattle gas station toward the end of this P-I story.

Even with gas prices back on the brink of $3, I hadn’t thought much about the possibility of not always getting what you pay for. But one cup out of a $3 gallon would be more than 18 cents worth of gas — and in a fill-up, that could add up fast.

By the way, looks like they kinda need some West Seattle gas-price spotters at this site — I chose “SW Seattle” (W Seattle didn’t appear to be an option) and nothing came up but a plea for tipsters.
