Countdown to waste

Dear Bags on Board and competitors,

I should probably hold on to this idea (it could be profitable) but I'm going to share it anyway because I don't think I'll be breaking into the dog waste bag business anytime soon.  I don't mind paying you for the privilege of having specially sized bags rolled up neatly around a little dowel that fits into a bone-shaped dispenser that hangs on a leash.

My one complaint is that there's no way to know how many bags are left in the bone-shaped dispenser.  Because the roll tends to loosen up as you use up the bags, the dispenser looks full until there's only one or two bags left.

If I were you, I'd label the bags on the roll with numbers that count down as you use the bags up.  That way, people would know when they need to refill the dispenser.

Who said there's no such thing as a free lunch?
