Surprise My Girlfriend!

For six months I worked at a place where I wasn't paid well and my boss was giving me a hard time. A month ago I saw no other options than quitting when he refused to pay me my full salary. This means I now have no job, which means no money. The only reason why I kept the job was becuase my girlfriend was worried about money. Needless to say she's more worried now.

I want to surprise her with some sort of "date night" where I can take her out to eat, or do something fun. Maybe she can relax and not worry for just one night. The only problem is that I don't have any money. I would greatly appreciate if you could help me out.
