AITA for telling another mom to pay for her kids meals and then walking out on the playdate that was at my house?

My kid is 5 . I work hard on teaching him table manners , how to be polite , how to have conversations with adults etc etc . <br><br>In general he is a very well behaved and matured kid. <br><br>A mom friend came over with her kids. <br><br>Her kids are 2 and 4 . <br><br>I made 3 chicken sandwiches for all kids. <br><br>When it was time to eat ,my kid got up to wash his hands. I told her kids to go wash their hands as well. The mom said oh they're fine and can eat with me at the table. <br><br>I said ok so let's eat. <br><br>Her kids started throwing food at each other and throwing food on the floor. <br><br>I excused myself and went to the kitchen to grab some more chicken to make more sandwiches because they were eating it fast. <br><br>When I came back I noticed both sandwiches were gone. <br><br>I asked the mom wtf. She said the kids were hungry so I made them sandwiches. <br><br>I asked her where my sandwich was. She said I could just go make another one. <br><br>I said I won't. Then I asked her to pay me for the 3 sandwiches. She said wtf I'm not gonna pay you for sandwiches I made for my kids. <br><br>I said I pay for my sons sandwiches when I'm over at someone's house and they make him food. I also buy him food when we're out. <br><br>She said fuck off I'm not paying you shit. So I grabbed my kid and told her to get out and said maybe I shouldn't have made lunch for her ass kids. <br><br>She called me an asshole.
