The choices were to either arrive very, very early (<8am) or you missed it. Then had to wait until around 4+pm when the early risers started to leave and move the car to a charging spot.
I mostly left after 7pm so it was ok but on days when I had to go at 5pm it was a big problem, didn't have time to get enough charge to get back home.
Also, there's not enough power available to feed all the chargers simultaneously. So when all chargers are used and charging, the power delivery dropped to ~1.5kW. As cars started to get full and stopped drawing power only then power delivery would rise later in the day. So there's no way to install a thousand+ more chargers, there's not enough power delivery available.
