An EZ Lube store in California overcharged Timothy for a new cabin filter when he went to get his oil changed. The mechanic managed to do this by quizzing Timothy on his knowledge of air filters, then using that info to make vague assurances that sounded good but didn’t convey the actual, final price. Timothy admits that he let his guard down, but when he was hit with the final bill, he regained his consumerist footing and began to take steps to remedy the situation—and he succeeded.
