Oh wow. This was with asking?
I saw the couple get in the Corvette so I asked what's them how much is it per day? He said he reserved a mustang and when he was at the desk( this was 2am so you first have to go to desk before going to aisle) she offered it at no extra charge.
So when she was walking us to the aisle I asked what other nice cars she has, so she said only thing she has left is the Maserati and she said she'd gladly give it to me
Forgot to mention that when I declined the offer she said that's a first! And told me I can bring the van back in empty
