Some aspects great, others just awful

The car was mostly fine. I gave it an avg score for cleanliness cos they gave it to us with some awful film smeared all over the windshield, rear window & mirrors, which dangerously reduced visibility. We couldn't see it til we drove out of the garage, in the dark, and it was too hazardous to stop on the roadside to wipe it properly. The counter staff were super friendly. But my god, did we ever wait a long time for our turn to drop off the car. Never seen anything like that. Moreover, when we picked up the car, the counter staff didn't say a word about the road toll system in Portugal, which is difficult for tourists to understand due to poor signage. With no reason to expect things to be different here than elsewhere, we hadn't read anything about it and were unprepared. So what happened is the 1st time we arrived at a toll plaza, we got in the "Via Verde" lane. OOPS ! And though we phoned OK Rent-a-car immediately after passing through it, and the person who answered reassured us it was no big deal and we could just pay the normal toll at any post office, that was untrue. Instead, we were charged the max. toll when we exited the motorway - 46,60 euros (!!!) - instead of just having to pay 9 euros. We were super pissed off. Finally, when we dropped off the car, we asked them to pls bring us back to our hotel, which was literally 10 min. away by car. We figured that was a fair request given the issue caused by them not telling us about the tolls (which they admitted was their mistake). But they refused and would only drop us off at the airport metro station or else the Oriente one. That added another 20 min. to our journey. I've rented cars in many places and they've usually dropped us off anywhere we wanted within reason.
