As an Israeli guy who traveled in south America i sure got to see the less positive side of the Israeli's , taking the chutzpa and not being a "friyer" to the limit, especially when traveling in packs like we often do. this is a normal behaviour for us Israelis , but this is just because we keep our eyes open, and don't take things as is, knowing that tourists are often an easy target for a good bargain. there are a lot of honest places in the world, hostels and restaurants who have earned the good reputation among us Israelis as a great place to come. and on these places you wouldn't find anyone say bad things about Israelis. we are a spicy combination of the Mediterranean temper and the Jewish Witt. i must say, the other side of the scale is no better. we Israelis often comment about the Americans, how they never just say what they mean. they will be polite, take their ability to form a fake smile into an art form, and the small talk into way of living. and i know this doesn't go for all living Americans, but i have the feeling you know what i mean. and you will excuse me for saying that, right? after all , what can you expect out if an Israeli guy.
