Golf Facilities: Focusing on What Matters Most via USGA.org
“An easy way for golf courses to streamline maintenance is by reducing the number of course accessories such as ball washers, benches and ornamental planting beds. Golfers do not need these accessories to enjoy their round and tending to them can take hundreds of hours away from maintaining the playing areas each year.”
Works for me. I don't remember the last time I used a ball washer anyway.
