We have 6 Chargepoint and I assume they are free, these spots are a good 10 min walk from my building and I never park there. BMWs and Leafs typically park in the Chargepoint chargers. We have three other dedicated EV spots that work off a 15 amp outlet. Other than that there are various 15 amp outlets people take advantage of, including me. I have the only Model 3 at my work and surprisingly I haven't seen a Bolt at work. I see mostly hybrids parked in the EV only spots charging.
