I don't own a generator myself and think they should be used as last resort.
Having said that I believe a lot in "live and let live" so if someone whips out their generator I am not looking to take offence.
I think there are a few variables. Honda generators seem to be a bit quieter than some of the el chaeapo ones and are therefore less intrusive.
Secondly in the busy season some aries get very crowded and therefore MH's are parked very close to each other. Finding yourself only a few feet away from someone's generator is really annoying. If the same generator was thirty or forty yards away it wouldn't be as bad. Lastly they should be used for as little time as possible and only when necessary. Turning it on to watch Coronation St on the TV doesn't constitute an emergency
Like most things in life there are some people out there with Gennys and they are considerate and responsible but I have come across a tiny minority who fit the description of a**h*le
I think the public would not be impressed if they were staying there....example I have seen people use them in the carpark of beaches where there were lots of non motor homing public around. I thought that was out of order
