Yes I did ask, but I didn't think my questions were 'stupid'. I don't really know anything about demo flights, hence why I was asking for people's advice.
I asked about the 'company pilot showing off' because I don't fancy being taken up by someone who just does barrel rolls and stalls and won't let me near the thing in a real life situation.
I asked about logging the time because regardless of how short the time is, or what I actually do on the flight, I wouldn't mind putting them in the logbook. I don't need the hours (or minutes, more likely), but I am happy to pay for the demo, so why shouldn't I log it?
I wasn't specifically in the market (although I do keep an eye out now and again), but I was approached by a couple of companies who think I might like to try out their aircraft after I made a casual inquiry, so I am giving them a go.
