Although we're not suggesting that the next time you visit a different country you try and make the locals mad, it's always handy to know what really annoys people - that way you can avoid being a nuisance.
Different countries and cultures have different rules of what is and isn't acceptable - and this is the thinking behind this funny series from online comic series Things In Squares.
The series lists the biggest no-no's you can do to different nationalities, from Americans to Italians and more, letting you know how you can avoid getting on their bad side. It is of course all a bit of fun - whilst breaking spaghetti in half before cooking it might not be the right thing to do we doubt you'll become public enemy number one for doing so.
