German Car Service owners David and Bruno are dishonest, and they discriminate against women.
They change car parts which are not necessary for them to do, and they deliberately use prefessional jargon with women, and they do not explain what they are saying making female customers confused.
They bait the customer with a lower price, then switch the price when the repairs are completed charing a more expensive price.
They threaten people by threatening to sell their car!
