Shawmut and E. Berkeley Parking Lot

Are negative stars possible?
I was really looking forward to parking here frequently through the winter since I just moved to the neighborhood, but will never return after the following has happened:
Incident 1:
There was no attendant when I parked my car in the lot over the weekend, so I put $ 13 in cash in one of these little metal things with slots, numbered according to the parking spots. When my dad went to get the car for me several hours later, the attendant was back and MADE him pay $ 13 again in order to leave.
Incident 2:
I just drove by there to park again this evening, and I started by asking the attendant about his system, assuming I was incorrect the time before, so I wouldn’t make that mistake again and have to pay twice. He completely disregarded my question and the following is what happened:
Him: You’re parking right now?
Me: Yes
Him: How long?
Me: Until 8 or 9am tomorrow morning.
Him: $ 26
Me: Your sign says $ 13 flat rate for 24 hours
Sign: $ 13 flat rate for 24 hours
Him: blank stare of indifference
Then I just left. Also, there was a gross shopping cart blocking the entrance to the lot when I arrived, which I had to get out of my car to move so I could enter. This place is nonsense, I’m not sure why anybody would park there.

This parking lot is where I used to park my car for work. It used to be $ 10 but for some reason went up to $ 12 recently with no warning. There’s a Tufts NEMC lot on Shawmut at Herald St. but you need to get on a waiting list for it, apparently. And it costs $ 6 which is B.S.
This lot is dirt and has the biggest drop off when you exit, you will certainly bottom-​out unless you own a truck or SUV. I kick up a lot of dust, then have to roll my window down to pay the guy (I’m sure it’s worse for him, especially because he’s there until about 6:30pm. Not sure when he arrives, don’t care to find out). There are no distinct lines, so you make up your own spot, but don’t park more than 2 feet from another car or he will make you repark. I’m not even kidding. Do I look like I’m kidding? The lot has like 80 spots and is never full. I’m about to repark this car somewhere…
If you come at a certain time which I have not figured out, but have heard this from others, there is no attendant and you can park for free, but it’s after regular business hours and you can probably find a spot on the street anyway. Still, I’d like to go sneak in so I could feel like I’m getting some redemption for the story below.
I left one day in the middle of the day and had to pay again when I returned an hour later. Come on, I paid this morning for 9 hours of parking, I left for an hour and now I have to pay again? $ 24 for 8 hours of parking. Unacceptable. Two stars.
