Coming back to yerent.
I had some nasty surprises there.
They (Sixt) added all kind of new taxes (as the regular taxes were included).
Season taxes, peak taxes,...
I asked them as Sixt has an orange logo, doesn't that deserve another tax...
There were 3 accidents (=traffic jams) on the way back, so I didn't have time to refuel (I had a flight to catch).
I had used exactly half of the fuel, and they wanted almost $200 for it....
I asked them whether I can sign for payment (they iron the credit card), and I will see if the check-in goes smoothly I'll return to refuel, but they didn't let.
As I spoke english to them,they figured that I don't understand the slang they speak, so they started making fun of me; so I stood for some 10 minutes before the door and scared customers away. (between 2 and 30 seconds walk you have different rental companies).
I must say that I was pretty successful at it ;-D
They finally apologized and begged me to stop.
