The poll of 15,000 European hoteliers has ranked Indian tourists as the second worst, next only to French.
Trailing India in the league of terrible tourists are the Chinese followed by the Russians and Brits, the survey by travel website Expedia said.
The Japanese are voted the world's best tourists, followed by Americans and Swiss.
Among the 10 categories that hotel managers were quizzed on, Indians fared the worst on the politeness front. While the Japanese could not be faulted on their manners, Indians were rated the most impolite.
And with most Indian tourists travelling to Europe with their own chefs in tow, it is not a surprise that the European hospitality industry views them as the least interested in trying out local cuisine or sampling local specialities after the Italians.
"We ate Indian food everywhere because that's what the others on the tour wanted. Imagine eating chhole-puri on Mount Titlis in Switzerland and being served samosas while watching Paris' famed Lido show! It was such a let down," said Bibli Das, who was on a European package tour last week.
Cleanliness does not seem to be a strong suit either, with those in the trade saying Indians leave their hotel rooms in a mess though they are not as messy as the Russians. The Germans were ranked as the tidiest.
