Reference Questions, 3/26/10

This is my first Friday shift ever. I have heard that they are usually quiet. We'll see...

1. Been here for over an hour and have not gotten a single question
2. Two hours and no questions
3. Wanted to know if I had change for a $20
4. Needed a guest log in and wanted to know what time the library closed tonight, was open tomorrow and closed tomorrow.

Two questions?! That's it in 3 hours. And I thought it was slow during the summer.
