Most places that have self-serve fountains charge for the cups. After that, they don't really care, otherwise the soda would be behind the counter. I had a friend that worked a Burger King. He said the cups were way more expensive than the soda that went in it.

I agree with Vash. Teach your kid and keep out of it.

For me, here in NY, being nosy can get your butt kicked, or worse.
