AITA for canceling my brother and his wife's wedding reception after they uninvited their boyfriend/girlfriend from the after party?

My brother and his wife (27F) are getting married. Originally, they planned for their boyfriend/girlfriend (23F&24M) to just attend the wedding, but my wife (25F) and I (28M) suggested they could come to the reception and we'd even set up something for them after the food is served since the whole event lasts four or so hours. They said it would be great if we could set up something for them to hang in the after parts since the more fast paced parts would still be guest only.<br><br>The wedding goes off without a hitch, and we allow the BF/GF to hang out during the reception. The food is served, and the BF/GF mingle with some guests. Then around 11, we set up the photo booth for everyone and the BF/GF. During the photo booth, we hear one of the brides ask the BF/GF where they are. We pull the plug on the photo booth, and she comes running over. She says they told them the after part is only for them and to leave immediately. I mean, WTF.<br><br>So as a revenge, I decide we're closing down the reception. We grab our stuff, all the leftover food and alcohol, and leave the wedding rather abruptly. The bf gw get their money back, as do people at the bar. Everyone gets a boxed meal to take home or eat in their cars. The rest is brought to my sister's house where we have a small party of our own.<br><br>Please let me know!
