I recently moved to a new apartment and, given that it is in a narrow and busy street with very limited parking space, I requested the reservation of the parking space to Traceroute SA, the company in charge of putting street signs on behalf of the Geneva traffic office.The fee reported on their website is 100chf.

Well, today I got the invoice for twice as much: 100chf for the signs placement, plus 100chf for "intervention". My guess is that this is the charge for the removal of a car who was parked in the space despite the signs (I called the "gendarmerie" to have it removed).

Now, given that I did reserve the space, shouldn't the intervention charges be paid by the car's owner? it doesn't make any sense to me that I got fined for someone else's infraction.
