One of my clients just moved into a brand new office tower. Everyone was all pumped about the new digs - lights that have movement sensors that turn off automatically when no one is in the room and turn on when someone comes in, new desks and chairs, new faster elevators,etc. However, upon using the 'facilities' for the first time, I couldn't help but notice a common problem I see in many public bathrooms around the city. Paper towel fills up the garbage cans too fast. Nobody wants to compact it with their hands. Inevitably, it overflows before the janitors make their rounds.
My business idea this go round is to import/sell garbage can compactors to these public buildings in the city that have this problem. Other places where I've seen this issue (besides busy office tower washrooms) are airports and universities.
