Sun Gas Station Crooks ...Want to pay $5.699 per gallon? $2 more than the staion 1/2 blk to the north? Orlando, Florida

As always returning your rental car filled with gas you try to get as close as possible. Driving into the airport on Semoran Blvd just south of Butler Naitonal Dr I pulled into the Sun Gas Station.  It looked like a cheaper station, think 7-11 (which by the way is a 1/2 blk back and $2 per gallon cheaper), I started pumping the gas.  Thinking my fill up was going to be approximately $15 for a half tank I was quickly there.  $20 I looked again and then $30 popped up (real quick) and I stopped pumping.  Only then did I look around to see a price and could not see one posted.  Looking on the pump only then did I realize that I was being charged $5.699 per gallon.  Of course the attendant was rude (I figure she had to have a cold exterior to put up with irate passengers all day.  Every day.  I hear the city of Orlando is trying to stop this thievery...the sooner the better.  Apparently the same owner has another one just up a little further so beware of that one also.  I turned around and finished filling up at the 7-11.  What a bunch of crooks and a black smudge on Orlando.
