KDs drinking in the house!!! What gives?!

I have seen multiple tik toks of KDs drinking in their house. Now I’m aware this may happen in other sorority houses as well, but it’s not advertised as prevalently IMO. The KDs don’t even seem to GAF so what gives??? Are they given special treatment bc they’re OR or what??? Like they have photo evidence of drinking in house even with their house mom in photos.
