You have been doing your job with a car that you rented for a few days. Let’s say it is Friday, and you have to return the vehicle. As you are giving back the keys and waiting for them to check the vehicle, they present you with an invoice that now has $80 more than you expected.
When you query this, they tell you that you were supposed to bring it back by noon, not now, at 4PM. You didn’t know about it because they never mentioned the time of the return in the beginning. They either invented the “late charges fee” on the spot, had it written on a very small sign behind the desk or had it in the fine print.
How to avoid: always be aware of all the details before you pick up the car and make sure they are written down.
