Dear Mary: Should I pay to charge my electric car at a friend’s house?

Q. An acquaintance suggested organising a celebratory dinner in honour of some mutual friends. He asked my husband and me, along with the other proposed guests, if we would all contribute towards the cost. The evening, in the private room of a top London restaurant, was a huge success and, as agreed, the organiser paid the bill and later sent us all emails with his bank account details to reimburse him. We have now heard that the friends in whose honour the dinner was held are under the impression that the party was paid for solely by the organiser and have been singing his praises ever since. I am not suggesting he misled them, but they may not have been concentrating if or when he explained it was — financially at least — a group effort. Mary, how can we tactfully let our friends know that we all chipped in on this enjoyable evening?
