I'm going to deny goody bags to kids
Why would you deny them goody bags?
I hate it when parents take advantage of my getting-to-know-my-kids sessions with goody bags.
It's not right to be so disrespectful, especially towards kids. You should learn to relax a little.
I'm fine with it and those parents know it's wrong to manipulate me.
You may want to punish the parents, but it's actually the kids being hurt. If you don't like the parents, then don't have the sessions at all.
