1. I'm 6' tall. 2. I don't like to spend extra time and effort to accomplish a task, and 3. I empty the kitchen trash (it's a fairly small can so that we don't accumulate a bunch of smelly trash before taking it out). I thought, "How about locating the kitchen trash bags on the counter so that I don't have to crouch down to the floor or head to the pantry every time I need a new bag... and how about making a dispenser so that I can just grab and pull, without any hassle..." SO I DID. :)
I hope this inspires you to find new ways of saving time and effort (not to mention prevent back aches) in your own home. :)
