It was probably during dinner when Dolores was probably many drinks in, that she got a bit nasty as she often does when she drinks a lot. This time it is not at home or in her office, so she has a bit of an audience. She started chatting mainly to her table about the Wandless and how they are just lazy-layabouts and don't deserve the attention they are getting. The stole magic, they registered, so they aren't criminals but they don't deserve the attention because honestly, they don't deserve to be part of the magical world. She is like can't they just go home or disappear. She probably continued on in a similar vein.
