Your view on a parking fee is sought

I've been in a similar situation, albeit not with a single seater, a couple of times.

I had a polite haggle to try and keep the bills sensible, and of-course to understand the size of the bill. Ultimately, they are legitimate businesses, and as I'm not a regular customer, they don't have a particular reason to cut me a lot of slack, so I couldn't really expect significant savings.

I paid the bill each time, said thanks for their help, and filed the bills mentally for future reference. Stranded aeroplanes are an expensive hobby however - although I also prefer not to trailer if I can avoid it, mostly because of the amount of damaged almost inevitably caused trailering any aircraft except in a specialist tailored trailer.

If you have such a trailer, you were daft not to de-rig it and take it home of-course. Taking the wings of pretty much any single seater is at most a couple of hours work.
