^ Yes! Have experienced some similar gents, generously offering a coke after changing a timing belt for them
You should get what you pay for, but the prices they officially fetch in german 'brand' garages are imho unreasonable and often not worth it.
I am aware they have to pay for storing spare parts also for older cars, or for paying the avilability of a quick spare parts delivery. And you get a guarantee, but.. two Euros for a minute
Most mechanics at the "brand garages" are not able to pay their own prices, this was different some 20 years ago.
