I'm 19 I'm afrad I"ll get fired from my job...

I worked my way up at a the keg and I am a new server.

some of the new servers have had experience serving at other jobs and now they work at the keg which is higher end

I think I have communication troubles or something. I mean I really try hard to do well. I don't goof off or not work

I had a job at 16 and was a cashier at rona. I almost got fired from that becuase I had trouble doing the cash off sheet
don't get me wrong, I'm not stupid. I just finished a year of college and am oging into nursing.

does anyone else have this issue. I seem to work better on my own than in a group.
I like serving though and I wnat to do well at it. My manager told me what I was doing wrong and what I should do to change it...but I'm still scared that even if I try to fix it I'l still screw up...maybe it's jsut the trauma from my first job...I'm not really sure... helpp
