Just be careful when doing 'foreigners'.
Some bosses have put GPS trackers in their vans.
Not a great way to end a working relationship by being caught by your employer for using his equipment for your own benefit.
Just remember
There are more plumbers looking for employers - than employers looking for plumbers.
Im pretty sure they have to let you know if there's a tracker fitted to the van, not 100% sure though.
