I have encountered mechanics who expected a hefty deposit or pre-payment for truck parts and turned out to be trustworthy. One told me that he had experienced quite a few people who had him start on repairs requiring expensive parts and then couldn't pay, despite having been given the cost up front. So this is a fairly commom practice locally. Some places stop requiring this after a relationship is established over time, though.
