When should my food stamp benefits start?

I spent a huge part of my day on Thursday to get food stamps. After I was called to the back they told me I had additional things to turn in before they could grant me benefits. I said ok and took care of 2 things on the list. I got fingerprinted and they gave me my benefit card. the next day, we went back to take care of the rest of the things on the list. I was told they would start that day. but still nothing. It is Saturday. I am just hoping they don't start till Monday. we need some food. Does anyone know about these things?
