Don't pretend to know my job!

Ever notice how most of my entries lately are me ranting about how obnoxious my job and boss are? I have. Sorry about that. One of these days I'll even do a couple of entries in a row that aren't. Today isn't one of those days.
My boss called me into her office today after I finished my work to "talk" (I always know when she says that, I'm going to come out of it a little upset). So she informed me of all the things I've done wrong. Of course, most of the things I actually haven't done wrong, except for today. Marj (one of the residents) decided after waiting for about two minutes this morning, that she wasn't going to stick around for the rest of breakfast. I'd already given her the fruit cup that everyone gets every morning, and had offered her a drink of either milk or juice. She ate her fruit, but refused her drink. So I figured, okay, lets get her breakfast quick then, so she'll have something to eat. I went into the kitchen to put the french toast on the griddle. Before they were even halfway done, Marj got up and left. Well, she's done that before, while I'm trying to cook her breakfast, so I figured she'd be back soon and she just needed to go do something in her room. That's what usually happens. About half an hour later, after I've fed everyone who was now out, one of my coworkers came out and informed (not me, the cook) my other coworker that Marj wasn't coming out for breakfast because she had waited too long for it. Now, she couldn't have been waiting in that chair more than five minutes between the time when I offered her a drink and the time she got up and left. Had she waited another two minutes, breakfast would have been ready (yes, five minutes later than I'm technically supposed to have breakfast on the table, sue me, I was tired), and she could have eaten. But she left, and I got in trouble for it. For the record, that hardly ever happens. In fact, I can't actually remember a time when it has. I'm sure it has, and I just didn't pay any attention to it, but that does show you that it really doesn't happen very often. The thing that bugged me the most is that I was explaining to my boss why I didn't have breakfast on the table right at eight, and she told me that I needed to have breakfast ready enough to feed at least one person at 0730. I like to see her try. And, although she tried to convince me otherwise, it would be a complete waste. No one is out by 0730 and ready to eat. She tried to tell me that Anne is, but this morning she didn't come out until between 0830 and 0845. Even when she does come out early, she asks when breakfast will be ready and I tell her how many more minutes until 0800 and she wanders around trying to exercise her legs. Every one of the residents are perfectly fine (apparently with the exception of Marj) of waiting until 0800 to eat. My boss is the only one who seems to have a problem with it (and, again, apparently Marj some days). Sometimes I really wonder if my boss is just trying to come up with things to blame on me. Because about half of the things she accuses me of, even if they were true, would be a bit of a stretch, that most people wouldn't have a problem with. And the other things that are true, only happened once or twice, are easily fixable and really, all in all, not that big of a deal. Yes, back when I was in charge of meds, and I was messing those up, that was a problem. There's a reason I asked her to make it so I wasn't in charge of those anymore. I don't want to hurt those residents. But getting upset at me (fortunately she wasn't too upset at this, or I'd be questioning her sanity) for stopping her from putting a dirty dish in my clean soapy dish water so I could rinse it off first, is a bit excessive. And ridiculous. I know my job. I know what those residents want for breakfast better than anyone, I can almost guarantee it. Ask me any question about breakfast about any day and any resident, and I can answer it. (As long as it's actually pertinent, and I wouldn't put it past my boss to ask a completely impertinent question and get mad because I didn't know the answer.)
Anyway, I've gotten that out of my system. Good night.
