For waiting until the last minute to tell my coworkers, this was my last shift

I (31f) have been working for the local bar for a year and a half, they close down last year with no notice. I returned at the end of May to help out in the kitchen, we had our second kitchen person and quit out of the blue, it really screwed us over. He never pulled his weight anyways. The rest of the summer it was just me doing open to close five days a week non stop doubles and coming in on the sixth day to put our truck away and deep clean. For the past almost 5 months it has been just me. During this time I was appointed the manager, at the time I was a manager of myself. We’ve had a full kitchen staff for October and I decided I would cut back my hours. And let the people I trained work. I am a mother with two children, I have responsibilities outside of work. I missed out on my children’s summer vacation, I had to cancel plans. And it got to the point I just didn’t make plans. the past 2 1/2 weeks, I have felt a very uncomfortable vibe from two of my kitchen people 24 (m) 20(f) they are a couple, and with how good the female was doing I figured they could handle it. Obviously they could not, and it was made clear today just how much they could not handle it. Instead of speaking to me about it when they first started having these feelings, they talked to everyone else. On my way out, I told them to give the owner their request off because today is my last day, I also stated that if they had these feelings, they should have told me. The guy then follows me out to my car and proceeds to scream at me about how disrespectful I have been, their manager for correcting them when they’re wrong, getting mad when they don’t do proper closes. Screaming at me about how I do nothing and they do everything. We do barbecue and smoke all of our meat. He did not give me a chance to get a word in edgewise to tell him that we have both talked to the owner about issues, and both of us have been blown off. I feel like if we were able to have a sit down conversation with our owner present it would’ve ended differently. I have asked the owner for support on multiple occasions, there is never a follow through. I knew last week that this was a toxic situation and I needed out. I did not feel like I could talk to these people on my own.
