Sorry to answer an old query but I just stumbled across this thread looking for a different dealer's charging arrangements.
Yeomans of Waterlooville (aka Nissan Portsmouth even though they're 10 miles away !) used to make their rapid charger available 24/7. That changed to 'office hours only' in Nov 2018. But as TVEV pointed out there is an alternative rapid charger on the nearby petrol station forecourt. Alas, they're not free and probably don't do complimentary coffee either so I'll try & get to Yeomans during their opening hours..
