"The mojo is gone"

I remember when Ronaldo came back to LA after being here in London and he said 'Fers, the mojo is gone'. I think it kinda happened to me as well.
Until a week ago I thought things were going pretty ok at the job. I was getting along with the manager and thought I was improving, maybe in a way that within a while I would be promoted to do cash up or something. I was wrong.
Apparently people are not enjoying my work there and the manager told me today that 'there's been some complaining for the staff' - the staff meaning the easterners.
Man, I think they want me to quit or something. They sure have a problem with me and it kinda got me so frustrated because I'm trying to do the best I can to learn everything.
The manager said I have to start doing things without being told what to do. The problem is, when she tells me to do some kind of job five minutes later another person comes and says I mustn't do that. What is that, man? Are they fucking playing with me or something? I'm too old for this shit, man. I'm not there to have a ball with friends, I'm there to do my fucking job and go home at 8pm and get paid on Saturday, that's it.
Again I ask myself: am I that dumb that I can't even do something that basically anybody can? Hey man, I'm just trying to do things properly and sometimes getting the job done and being fast can't be in the same sentence. The manager was nice, though, I think deep inside she kinda likes me, otherwise I think I would've gotten sacked already. I know exactly who's been gossiping and I just hate their fucking asses for that. Especially the "chef", who's actually a fucking cook. I think he didn't like when we argued about the sweeping. Oh, he's the great authority and I said my thing and he sure doesn't like when people don't do as he says. He's a bastard, alright.

I don't don't know what's gonna happen now, I might be fired, I might stay there. I'm sure looking for other things to do.
