Premise: and well i know once when we had a we usually round inspection time we find out there's something wrong with our car but um once the muffler needed to be changed and uh he had looked at it himself and but we saw a commercial for like fourteen or twenty dollars or something for a change he said that's really really good so he went in and uh but when they quoted him a price they really wanted fifty or something anyway but the car that the muffler people had um my at least my husband felt that they had damaged the muffler further you know they had punctured a big hole in it when it really could have just been patched or whatever and so since then i don't think he's ever even seriously considered a you know any kind of job he thought he could do himself

Hypothesis: The muffler shop charged my husband fourteen dollars.
Relation: contradiction
