pguillem : I was surprised that pnegyesi didn't lock it for you so I thought I could have a go at it. I didn't have to walk the dog as I don't have one, but last night I had to finish some work before looking for this bus : I started searching just a few minutes before posting the solution, so we were pretty much in the same situation.
pnegyesi : I think the licence plate says Zarrin (with a heavily stylised Z) and not Arrin.
