Two faced teacher

Man I had this teacher in my sophomore year and she didn’t allowed snacks in her class. I come in her class 15 min late since I had swim class plus I stopped by the cafeteria to get hot cheetos. (Yeah I know no snacks allowed but I couldn’t help it cuz I did some laps in the pool ight). Anyways I go to my seat eating and getting my stuff, she comes to me telling me to put them away I say okay. (also she is “nice” to students (〜￣△￣)〜

She leaves and I’m trying to make space in my backpack (I still had my cheetos out) she notices and I had them in my hand, she comes and snatches them out of my hands and walks away. Others noticed even the girl behind me, she told wtf is her problem. There was also another teacher in the class and he tells me to work on the assignment that their doing (he also ignored what she did :/ ) I just straight up tell him I ain’t working on this shit if she didn’t return my cheetos. So basically I didn’t do shit the entire class. it was kind of close to ending so I stand up to get them pack up and I leave early from that damn class. (other students tend to do that too)

*in the end she tells my dean that i “walked out of class” and being “disrespectful” of course he believed her n ends up giving a 2 hour detention to only me ╮(￣▽￣)╭
*the cheetos were basically my lunch :(
