Gas bar strikes me as funny, too! Gee, do they proffer a snifter of each octane so you can test the bouquet?
Our schools are closed today, too, and we only got about an inch.
My guess is that what you're asking about is called the lock-down bar or something like that, but. I just called my friend who works at a BP station, and he didn't know. But he said if he finds out, he'll call me back.
