Anyone get bad gas at the pump?

I had a bad tank a month or so ago in my Mazdaspeed 3. I always put premium in it too. Thing was down on power and mileage was noticeably below normal. Next fill up from a different station with pump premium was like NIGHT AND DAY. Happens. :dontknow:

Word of advice - if you see a tanker pulling in or out of a gas station DO NOT GET GAS THERE! Pulling in means their tank is low and the sludge will be in your engine. After it gets filled up, the sludge swirls around until it settles back on the bottom.
