I'd tell them, no question. You guys do realize that "sticking it to them" is only hurting the station owners, right? They aren't making money off gas. Its pennies of profit to them. Its not going to hurt the big name companies at all. Gas stations make so little profit, it would shock you.
Heck, $4 for premium is nothing. In NY, we are almost paying that for regular. I just put $20 in the truck at $3.91/gal. Some stations are right at $3.99 for 87. Premium is in the $4.30'*, diesel is $4.35ish.
