Use the scooters they provide for mobility-impaired people.

Note you shouldn't actually do this because you're taking away a scarce resource that might actually be needed by other people who can't walk, but it would defeat gait recognition. You can always bring your own scooter, but you'd have to bring a different one every time or you could be identified by the scooter. Since that would get quite expensive, you might need to pool resources with other privacy-minded individuals to maintain a shared group of scooters.
