Morrisons got it right with the choice of chargepoint speed when they put them in, 50kW which was state of the art for the UK then - 5 years ago. Their problem is the provider they chose to partner with (Geniepoint) who did no maintenance on the chargers and they were/are always broken. Morrisons got a reputation for being unreliable which persists. Geniepoint had some investment last year and started a refurbishment program, but put the prices up - now they are perceived as expensive and unreliable!

The Marston's pub charger is likely an Osprey one as they have a deal with them. Osprey are solidly reliable but expensive, so again people will avoid in favour of cheaper offerings unless on company fuel cards.

In my opinion, private owners shop around for lower prices or stick to home charging while the Tesla driving company car driver with a fuel card does not care about price. Company car drivers tend to be the ones public charging while out doing their job. There is no cost downside for them and the BIK saving is still significant.
