That is a decent rate for the flipflops actually. Back when I still hadn’t figured out what a futile exercise the relevant message boards were, I got into it with a local “entrepreneur” over the rates people were pulling for DSV etc.
He claimed he was making it rain for €.65 per km on European work. Which is of course lunacy, but if you don’t pay for the ferries nor roads, then fuel is cheap and €.89/km won’t put you in the poorhouse, given you of course get decent miles every week.
