You need to have worked in the catering industry for this one as you need to know how to fold a napkin.
If you go out for dinner nd you don't use on eof the placings the restaurant will use the napkin for another customer. So sneakily go to the loo with said napkin, wipe your bum with it, then go back to the table, fold it correctly and voila!!
