Dude, I hate to break it to you, but I don't think that was Ginny.

I feel like if she had a problem with salt, she probably wouldn't be chowing down on packaged gas station snacks? Good thing she didn't seem interested in harming you anyways.

Ugh, sorry you had to deal with all that mess, though. Inconsiderate customers are the worst.

A lot of people are suggesting you tear the wall down, but maybe don't do that? It's in the basement and you don't know if it's load-bearing or not. Doesn't sound like a good time and place to get sledgehammer happy.

Anyways, maybe look into moving out.
