Yes, you are right, it's really big.
If you compare, about the size of your scoots rear inclusive trunk.😉
But serious, here such a comment (from a stranger) would be considered very impolite.
No worries - I was just taken by surprise to hear this from a person in this village famous for it's gentle acceptance of others. Generally - hateful people are rare in this friendly community.
But, being a "destination" village on summer weekends - all kinds wander in.
As for my helmets - I never have been able to "stow" them inside a scooter or a top case.
Not in a Burgman 400, Forza 300, LIKE200i or it's Bestem 929 case, Piaggio Liberty nor in it's Piaggio top case.....
In the winter I just wear it like a warm hat into public places (grocers, donut or coffee shops, diners, McDonalds, etc.)
On warmer days .....I do the same
If I sit down inside, I take it off.
