There are a certain group of tourists from a certain country that are by far the worst. Like it's not even close. I don't want to say because I don't want to offend, but, you might know who I'm describing based off these descriptions.

They've just finished their military service in their home country and they go to South America in herds. They have this obscene sense of entitlement, which I feel may have been indoctrinated through their military experiences.

They frequently cut lines and then try to start a fight if someone contests. They steal. They get into fights with locals. They sexually assault the women. I remember on a tour of the Amazon, they killed an anaconda and took photos with it. Also on that tour, we had to share from a plate of food and they each took massive portions first and there was no food left for anyone else. They didn't care.
