Should i still go to work with Tonsillitis?

I'm a waitress and i woke up on Sunday morning finding it hard to even swallow some orange squash. I have work tomorrow and have already contacted them about my throat infection. I do feel queasy and get headaches but i don't usually let an illness get the better of me. Is it right to go to work even though i'm around food or am i putting the customers health at risk?
