A client called and said he needs a locksmith service because his fueling tank is locked.
Although I am old enough (55), I thought at the beginning this was a joke.
But when clients call and ask for help I took it seriously.
While I was driving to the client, I suddenly remembered that we had an old Volkswagen in the 70s, and we had a lock on the fueling tank.
I picked up the lock, and the client was very happy.
Client ask to make a new key and I sent him to buy a new cover because we don’t have these keys any more.
