Workshop prices – usury?

Hello together, I have to go back to work, because with my diesel (again) the pre-glow candle hops went. When I rummaged in old bills I noticed: wages 1999: 103 DM wages 2000: 134 DM wages 2002: I’m curious… The list of listed works could be about like this: 1. Entered into the vehicle 2. Driven into the workshop 3. Hood unlocked 4. Out of the vehicle 5. Hood opened 6. Diagnosis initiated 7. Diagnosis completed 8. Diagnosis completed . . . . . . In doing so the candle costs just 40 euros… Do you still carry this or go to free workshops?
