Well, and when you use chopsticks to pick up the sushi and put it in your mouth, they come over, slap the sushi off your chopsticks, slap the shoes onto your chopsticks and stand there, patiently watching and waiting for you to start chewing.
And so you bring your own chopsticks so they won't be allowed to touch them, since they're not the chopsticks that the store provides, and they tape your hands to the table and try to force-feed you the shoes with their chopsticks, so you have to unstick your hands from the table, re-grab your own chopsticks, and fend your waiter off with one hand so you can pick up the sushi you want and eat it.
Only, the store is in your house. It's at your job, it's everywhere you go to eat and you can only get away from it by locking your access to chopsticks away in your own home. (Running linux on a personal computer and not having easy access to a lot of convenient software)
