It just comes with the territory when I ride my Brompton that I will be asked all about the bike. I prefer not to have these conversations as I just want to get where I am going.
The two most asked questions are, how much does it weigh and how much does it cost? I actually like when the ask the question of price first because that usually stops the conversation in its tracks from shock after I tell them.
These questions are just not unique to folding bikes. When I use my Burley Travoy trailer the same thing happens.
