Crossing Luxembourg?

Used to transit Lux while driving for a big Austrian firm Lindner, green and red trucks with British and Hungarian drivers .
Fuel up cheap, but a long way way round from Southern Spain to the UK .
Lots of forbidden signs off the main routes, so the locals lose out on revenue from drivers who cant get there .
Habay truck stop in Belgium used to do roast meat on a skewer .
Chunks of meat the size of a Rubicks cube.
Pizza outlets on Belgium Msa, like that .
Found Lux a weird country trying to impersonate the USA .
