Well, it was a crazy couple days.
Rumours were flying. That I was crazy, that I was a bitch, the usual. Work Husband walked out, too, and said them firing me was really proof that they didn't care about their employees.
The other part-owner said if I didn't come back, she was out, too. She got him to tweak the schedule so I only work with her (the other host does NOT like me and that was part of my frustration), so basically I got the good money days and I don't have to deal with him. I didn't really want to go back after all that, but I didn't want her to leave and I couldn't pass up that opportunity. I'm making the same amount of money, if not more, working one less day.
Boss-man is too prideful to admit he was wrong, but I swallowed my own and apologized. He apologized in his own way - he asked me if I was okay and said he was glad to have me back. It was a little awkward my first day, but most everyone was on my side and excited to work with me again. Big ego boost. He gave me some hostessing hours while one is on vacation and he, the customers, and the coworkers love the way I do it. I might take one or two permanently, it's kind of nice to be there not in uniform and running the show.
Basically, everything came to a head and turned ugly, but all worked out in the end. We'll see what happens when He-Who-Does-Not-Like-Me returns in two weeks.
Work Husband got a new job and has become Real-Life Boyfriend - we'll work on the alias.
