I worked in a casino that had a wool carpet. When the carpet was new it was ridiculous the amount of static that it generated on you. I was wearing steel toe non slip and anti shock shoes too!

I quickly learned to hold my machine keys ring (3 inch wide ring) and tap it to the slot machine frame. Often a three inch violet spark would jump and I could even feel my clothes move. One time I even causing one of the slot machine player tracking system to reboot, it was that or me better it got the hit.

A manager said at a casino they used to work at they would spray fabric softener on the rugs to alleviate static. I don't know if it worked or not.
