popcorn- and bread-feeding feeding melees of hundreds of other feathered

Does anyone have any suggestions for a nice tactful, friendly, educational
way to say to these people that they shouldn't really be feeding these
birds? I particularly want to say something where signs clearly post "No
feeding the waterfowl" yet here's Mom and Pop teaching Junior that rules
apply to everyone but them. I know it won't matter to some people, they'll
do what they want, yet I do believe a lot of people think they are helping
by feeding stale bread to hordes of mallards, etc. And what do you say to
someone who says it's no different than putting out a birdfeeder?

Any thoughts?
