What does Mr. Logan tell his kids about Wallace's store, and what does this show about him?

From the text, we can infer that Papa is a strict man, who expects to be obeyed.

“Your mama tells me that a lot of the older children been going up to that Wallace store after school to dance and buy their bootleg liquor and smoke cigarettes. Now she said she’s already told y’all this, but I’m gonna tell y’all again, so listen good. We don’t want y’all going to that place. Children going there are gonna get themselves in a whole lot of trouble one day. There’s drinking up there and I don’t like it—and I don’t like them Wallaces either. If I ever find out y’all been up there, for any reason, I’m gonna wear y’all out. Y’all hear me?”
