There's some kind of psycho-neurological factor that determines how different people interact with physical controls to a virtual environment. Some people's brains inherently grasp that when you push a joystick or button far enough to engage the switch (or to complete saturation in the case of analog), pushing any harder doesn't make your character move any faster/jump any higher, etc. Other people's brains never really accept this (even if they're consciously aware of how it really works).
Back in my C64 days, I had a virtually indestructable microswitch joystick (it had a five-year warranty). I used it for a couple years without incident, but as soon as my brother-in-law played a couple games with it, he broke it. The thing is, my brother-in-law is this really reserved, careful, methodical (and very intelligent) guy, but when Ms. Pacman wasn't going to make a corner fast enough, he just couldn't help but direct every bit of strength he had into pushing the joystick harder.
The moral is, when you build an arcade cabinet, you just have to build it to withstand people pushing, pulling, and slamming the controls as hard as they possibly can.
