I believe this scene in the pub was just after Rumpel kicked her out of the castle, she probably vented a lot on her way to the village and arriving there she just needed someplace to sit, think and let everything sink in. Much like all the people in SB, who go to Granny’s. (Anyone realised yet, that they show them drinking alcohol a LOT? Practically every episode there someone in need for a drink.)
AND THIS ON A FAMILY SHOW… PROHIBITION NEEDS TO BE ENACTED HERE. 🙄
