Mia's 2008 Toyota Sienna XLE minivan was making strange noises, so she took it to the repair shop. She explained to the desk clerk that she was planning to sell the car soon and didn't want to put much more money into it, so he should check out the car and then either fix the problem (if the cost would be less than $300) or call Mia for instructions if the cost of repair was more than $300. The clerk, Bob, neglected to write down on the work order the part about "before beginning work, call client Mia for instructions if the cost of repair is more than $300," and the repair shop employee who inspected Mia's car went ahead and fixed it at a cost of $3,000. When presented with the repair bill, Mia refused to pay. Bob admitted that he failed to relay Mia's instructions to the repairman but told her that the car was not safe to drive in its prior condition, so she would have had to have authorized the work anyway.
