We all hate those nasty drips from the water, lemonade, iced tea, punch, etc. dispensers that just grab that last drop and wait until the cup is moved away to let go of it. I have a wintertime plastic "boot tray" that usually lives on the porch in the winter for wet/muddy boots and shoes. It has a nice lip on it - maybe 2 inches deep - and is long enough to fit under several drink dispensers. Light bulb time!
I'm going to put a couple of old "car wash" towels inside the tray to absorb the drippies, and won't have to worry about mopping the multipurpose room floor after my son's Eagle Scout Court of Honor!
