lunch lady.

We have a lunch lady that comes in every day (she's getting paid but b/c its Pre-K she comes INTO our class every day) & my asst & I go to lunch. Am I supposed to get her a gift?

Also, she works w/ the K teaching asst. at lunch. If I got for the parent (not in my class) do I have to get for the K asst too??

What would you do?
