Would you help

Don't worry about it. 

The vast majority of people on campsites are fine. 

I would have told them we were only moving because of all the ants 

That was unnecessary of her Tracy as Fysherman says people are usually quite good, I would have offered however now if something is amiss I would try the nearest van and ask.  

not every offer of help is appreciated as help. I assume you were blocking the site road, you don't say how long they had been waiting but she might have had a time table to make.

That scenario did cross my mind as well. Generally I hook up and tow off straight away and do my light check, open heater drain valve and check mirrors once I've got the van in a straight line and where other stuff can get round me.

We always do our light checks, drain down etc while on the pitch. We then pull off and when the car and van are in a straight line we check our mirrors. We even have a check,list which we use which is in the handbook to make sure we have not missed anything, just in case.

I wouldn't have battered an eyelid at the comment. It seems a perfectly reasonable question from someone who wants to get on their way. I may have asked for their help and explained we were new to this. Of course, if she grabbed me by the throat and spoke in a nasty tone, then that would be different. 

When we caravanned, we did our lights check and mirror checks where we didn't block in people.

Don't worry, though. The vast majority of people on CC sites are pleasant enough.

the caravan was still on it pitch, we pulled the car in front, they could not get out as he could not get his car in front of his caravan due to use being there, i always do my mirrows and lights a straigt line so we get a proper picture, and then  check the lights, ten minuets earler we had been approched by a gentleman and his wife it was there first time and had blown there elctirc, we help them, and we now not a lot, i hate stuffy people who think they own the place, i abide by the rules and am resposible and quitre we were struggerling and dont like to obstruct people  and try our best not to, but some times things dont go to plan, and we all need a little help at some point.

Totally agree with you OP, if the woman was so desperate to leave then why not offer to help? Some people eh!

to all those who drain down on the pitch hope they do it only on hard standing as hot water on grass kills it. A friend who had a CL on grass had in the end to tell people when they moved on to the CL that draining down and dropping the hot water tank wanot allowed, 

There was a horrible scar on the grass at Pembrey this year - it must have been a very big water tank.
