Another Britpick Question

[amberfocus]

Okay, I need the British word for what we call a napkin.  I know what you call a napkin is what we call a diaper.  What we call a napkin is like a specially folded paper towel they give out in restaurants that don't have linens.  In Canada it's called a serviette.  Same for you or is there another term?  Thank you.
