I think I'm about to get fired

My wife and I work at the same restaurant. I'm a server she's a host. It's an upscale place.

I had a co-worker that I was friendly with, he works in the bar and as a server, just mysteriously stop speaking to us. I'm talking, look you straight in the face and say absolutely nothing after you ask them a question kind of not talking. Neither of us could figure out why but it wasn't a big deal as we are transferring to another store soon, a thousand miles away.

But it became a big deal the other day when he and I had sections next to each other. It was time for me to say something to a manager because I didn't feel like there was going to be any teamwork and our restaurant is built on it. They moved his section and he was a pain in the ass to me all night long, making snide comments and just being a dick. Near the end of the night I decided to do some of his side work as an olive branch but to no avail. He was an even worse dick after that. He even got in my face at one point.

So, the next day I brought it to the GM's attention and even told him to go check the video of when the guy got in my face. He basically said he was tired of dealing with this and told me to stop trying to be nice. I called him a feckless manager to his face. He didn't know what that word meant so then I got to call him spineless to his face. I asked to be cut because I was too furious to put on a happy face in a place like that. They obliged.

I'm off today but my wife was scheduled to go in at 4:00. A different manager called and told her they didn't need her tonight. On a Friday night. Very suspicious.

So I put in our 2 weeks notice in an attempt to save face and save the transfer to the other store. But I have a feeling we're getting fired tomorrow when we are both supposed to go in.
