Help with groceries (Missoula)

I started a new job and don't get paid until Tuesday, I probably won't be getting a full check and my pantry is currently empty.
I normally wouldn't ask for help but the food pantrys are all closed until Tuesday.
I can offer work in return.
I don't even need much myself but we have children and grandchildren living with us.
We just need to make it til Tuesday when I can get to a food pantry really.
Any help is appreciated.
