I've been a global traveler for more than 5 decades, now settled in Thailand. My worldwide experience (the macrocosm) concurs with the opinions and experiences of the Phuket hospitality industry (the microcosm). A lot of these arrogant international tourists seem to be unaware that they are a guest in a foreign culture. The level of respect and lack of common courtesy is the modus operandi. Israelis in particular, in my experience, present the most abhorrent behavior, eg. used condoms left under pillows for the room maid to find. Groups of Israelis sitting on the footpath, legs stretched out, deliberately obstructing pedestrians. Israelis aggressively pushing their way to the front of a queue, talking loud, shouting at staff. I have a long time friend who owns a souvenir shop in Kathmandu, Nepal. He told me that Israelis are by far the worst customers. They swear, curse, abuse and intimidate the shopkeepers. They accuse them of cheating and try to get unreasonably low prices. My friend was even spat upon after declining a below cost offer from an aggressive Israeli.
