There are malls everywhere in Hong Kong. They're usually woven into the concrete jungle, connected by sky-bridges and tunnels. Often times they're built on top of a subway stop, with more housing and apartment space above. So, potentially, a person can take care of all their daily needs in Hong Kong without ever being exposed to sunlight, or walking really. Apartment to elevator to escalator to subway to escalator to elevator to office to elevator to escalator to subway to escalator to shopping center (including foods) to elevator to apartment.
The closest subway-stop/mall is a 10 minute mini-bus. I like the store at my usual entrance. It's called "UNI QLO." Every time I see it, I think of David. He'd start laughing and then show Alban. Alban would stop. Point. Tilt his head. Then David would tell Alban to go get a picture with it. Phil would catch up with us around this time and ask me where everyone went. Then he'd see them, a second later he would see the sign and start laughing.
Cody would be busy buying fro yo at the other end of the mall.
