I am sorry you recall the conversation in this way as it certainly isn't miine.

I checked all pitches in the morning to see which hook-up each was connected to and I spoke with all guests who were out and about, including your daughter who was packing the car boot. I picked up some small litter between your car and the empty pitch.

You were leaving and emptying your toilet waste but actually stopped to assist your daughter dragging the wastewater. You didn’t have to stop emptying the cassette to talk to me.
At no time did suggest you had an awning heater, as you clearly had no awning, but said in the past it had been an awning heater which caused an excessive usage. I asked about usage as I was concerned it might be our new system error rather than your caravan that was causing the excessive use.

I explained that we have just fitted a new system which will go live shortly where all hook-ups are monitored (and guests will pay for electric used) and you used £13:85 overnight; the next nearest was £6:55. We charge £5 per night at the moment for electric.
You paid £43 for the weekend, Pitchup take a commission and pay us £34:73. We pay VAT so receive £29:99. We know that between 6pm to 10am you used £13:85 (44.66kwh), so it is likely that your stay actually cost us money.

Other guests used between 4.5kwh and 21kwh, it seemed only reasonable to ask if you had any special equipment that might have been in use. I am hoping that future guests will welcome paying only for the electric they use and that they can monitor their caravans to ensure they are not costing them excessively.

I thank you for your previous custom, but on this occasion I believe I asked a perfectly reasonable enquiry of a guest who was preparing to leave. It would have been foolish to wait until you drove out!
You are welcome to return once the PAYG system is fully operational.
