The best there is at what I do
We have an out of town McDonalds with a Pod Point charger and two bays marked up for EV charging use, the car park is far to small and at certain times of the day is rammed so it's inevitable that the charge bays are ICE'd, one of the staff seems to be using one as a personal parking space for his moped.McDonald's Car parks are mostly too small. Too much lost business.
It is a three-way intractable conflict;-
1) If you have customers with a dwell time of 30 minutes or less and you are packed at peak times, you don't want them there for up to an hour.
2) If you have customers with a dwell time of 30 minutes or more you don't want to hassle them with a 'move it after 30 min' clause
3) If you put in slower chargers you will lose the throughput of customers based on a business model of high flow rate.
There's a few out of town ones that would be viable, but mostly it wouldn't work.
McDonalds is a fast food restaurant and they don't want people dwelling for a long time, my last few visits have resulted in sending the food back because it was cold.
