Alright what are some cool shit you can see in warehouses?

Years ago I went in a Napa auto parts and the associates would gather up tons of little components (relays, fuses, bulbs) in these custom fabricated scooters with baskets on the front, and another basket/ truck bed thing in the rear. Looooong wheelbase they were really fucking fun to use. Policy was "no excessive speed".
Another warehouse had beach cruisers with custom trailers, similar deal. Wide open aisles, but again, small little parts where forklifts wouldn't make sense.
