Premise: uh uh-huh yeah well we have a lot of Mobile stations around here and i used to use that card almost exclusively but now they're charging the extra five cents to use your credit card and Texaco and Chevron and somebody else is not anymore they'll take it you know at the cash price or you they'll now let you write a check if you have their card so you pay for it immediately instead of um you know putting it off for a month

Hypothesis: There are no Mobil stations in our area.  
Relation: contradiction
