Eating food off of the ground
istock/_Image-Source In the Middle East, if you drop bread on the ground, you should pick it up, kiss it, and raise it to your forehead before putting it back on your plate. This shows respect for your food and the work that went into making it. (Find out the truth behind the 5-second rule.)
Not finishing everything on your plate
istock/bigjom In many Asian countries, wiping your plate clean means that your host didn’t feed you enough. Leave a small portion of food on your plate, instead, to indicate that you’ve had your fill—otherwise, your host will continue refilling your plate until they run out of food!
Playing with your food
istock/BraunS In Germany, cutting up your potato with a knife implies that you don’t think it’s all the way done. To avoid insulting your host, smash your potatoes with a fork, instead (plus, you’ll get better gravy coverage!). And no matter where you eat in the world, Napier-Fitzpatrick says, “if you refuse their food, you refuse their culture, which is refusing them. So you should at least try the food, if you can.” Be sure to follow these house guest etiquette rules when you’re a guest in someone’s home.
