My first time attending the PPAI Expo was in 2007. I ducked into the restroom between education sessions. For those of you who have never been in a men’s room, just know that every urinal has a splash guard in its basin, usually made of rubber or plastic. Only at the PPAI Expo, the splash guards were imprinted with the name and logo of an exhibitor and a call-to-action: “Visit us at Booth XXX.” Talk about a captive audience.
