10 Ways You've Been Accidentally Insulting People Every Day
3. Using The Left Hand
Sorry lefties. You'll have to get used to eating with your right hand if you feel like taking a trip to the Middle East.
In Muslim countries throughout the Middle East, using your left hand to eat or for any form of communication is considered dirty and rude. That means no shaking hands, accepting gifts, or waving with anything but your right hand.
The only time you should use your left hand is during your private bathroom moments, as this hand is associated with wiping when you are done - which is why it's considered so rude in every other situation. Don't be that person who grabs food with their left hand, grosses out the other guests, and forces the server to remove everything from the table.
