I shop at Mobile Mart ALL the time. Recently, I noticed even though I selected regular gas the machine charged me for plus. After pulling old receipts I saw that this happened often. I approached the owner with receipts and his response was that it was my issue. He has no control over the machines. Needless to say I will be taking my business elsewhere. I will be filling a complaint with the BBB and will make sure I post on any social media site to beware of the shady business practices at this gas station!
