A local car rental firm have come up with a great way to handle rentals with no customer contact. (Covid, dontchaknow.) They leave the car with the key in a combination lock-box hooked over one of the windows, and you sign the paperwork online and get an SMS with the lock-box combination. When you're done, you fit the lock-box to the window, lock the car, lock the keys in the box, and scramble the combination. Ignoring the fact that they're trusting a Master lock, that's actually quite clever.
Well, it's quite clever until they decide to give you a car with a push-button ignition, doors that unlock when you pull the handle if the key is near, and a key that's quite happy talking to the car through the lock-box...
The "Ohhhhh, shit!" I got from their rep when I called them about this was absolutely priceless.
My friend and I applied for airline jobs in Australia, but they didn't Qantas.
