Back...finally

I had to discontinue my internet for a while due to the economy's toll on my income. I have finally been able to reconnect it, although I am worried this will not last long.

Several updates...Katie the waitress is gone, Nina the waitress is in. I have been successfully working open to close on Friday and opening on Saturday morning for 8 months now. I have not taken any days off in that time.

This year has been slower than last. Usually over the summer I am able to make enough to supplement the slower winter months. This year I am just breaking even.

Last Friday we were closed due to storms, and next Saturday we are closed for the holiday. Ugh.

To all my friends here, I am sorry I have been missing and hope this doesn't happen again. I do need to ask for your help. Being in the same industry, your advice and input is greatly needed:
Last night I found out that another waitress has been asked to work with me on Friday nights. The manager that asked her said that they want another server because they "have to help [me] run food." They do not have to help take orders, get drinks, prebus, get refills, take carryout orders, or take payments. They only have to help run food when I have large parties because all the food is ready at once and we do not have food trays to take the food out. The waitress they asked to work is the one who told me, no one else has spoken to me about this. I am hurt by this, and angry. They are taking away half of my income!
I need help figuring out how to bring this up to management. The other waitress has agreed to work the shifts. Our hope is that after a few weeks of working together we can sit down and tell the manager that it isn't necessary to have both of us there.

Please help! Any and all responses will be greatly appreciated.
