New Job No Food

I am currently starting a new job and have just gone through training for 8 hours. Only problem is I am starving right now with no money until I am able to donate plasma. I am staying at a drop in shelter and unfortunately they dont provide food and I have missed any opportunity to eat at places that offer free food. I am training to work for an airport pushing wheelchairs. If I need to provide something let me know, but I could really use a few dollars to get something to eat tonight if possible, I don't think I can get anything delivered and I am on my way back to the shelter now. Any help is appreciated.
