Didn't your mom teach you any better?

Today I took an hour nap after class and barely made it to dinner. Well I had an adventure when I got to the cashier. Only the Korean lady was working there and this guy ahead seemed to have a little too much energy drink. He's kinda jumping around and looking like a hyperactive child. And the lunch lady asks him what he's got and he can't understand her. After repeating herself three times, he finally understands and tells her what he has. He pulls open his wallet for change because it only costs 70cents but he can't seem to find enough so he finally gives her a one. She gives him his change and hands him his receipt. Well he's trying to do too many things at once so he decided to finally grab the receipt with his mouth. The cashier got so offended that she goes off about how rude he is. And he tries to defend himself and she won't let up. He says, "well dogs grab things with their mouths all the time." And she replies, "Are you an animal? You're still not an animal. You can't be doing what animals do." So finally the guy walks off and she's still talking about him saying how rude he is. Then she looks at me and says, "How can he just do that? You know how rude that is? You can't be working at a government facility and do that." Well this was just too funny and I couldn't wipe the grin off my face. I just smiled and said, "Ya, people these days." Honestly, if I were her, I wouldn't punched him in the teeth with the receipt in my hand and acted like it were an accident. What's ironic is that you would think I'd be getting a scolding like that. But this balding dude beat me to the punch. Thanks buddy.
