Were you ever refused access to a place with your folded Brompton?

Interested to hear some stories about issues you’ve had while trying to take your folded Brompton inside public places (shops, museums, restaurants, hospitals, transport, etc.), as well as the craziest places you managed to sneak in to with your trusted companion.

PS. If you could share the country where it happened as well I think it would help understand the different nuances in how Brompton is considered around the world.
