I once got FREE gasoline at Murphy's which is the Walmart gas station. I could tell everybody how to do it but it would do them NO good since that deal can no longer be done. I did that back in the summer of 2012 when I not only got FREE gasoline at Murphy's but also FREE food at Walmart.
It was such a good deal that the first time I did it to get FREE gasoline I noticed a police helicopter overhead as I was pumping the FREE gasoline and PANICKED thinking they were about to arrest me but the police helicopter was only momentarily over me as it continued on to some other location.
LOL
