I returned from my summer trip and do want compare my personal feelings whith feelings another people.
Personal favorites of my Worst Tourists top is Britts. Always totally drunk, loudly, aggressive in big companies (but very quiet alone, cowardly), though mostly harmless ( their brawlings looks childish ). Often by own offensive actions create dangerous situations for yourself. Girls often looks terrible, fatty, cellulitis, ugly tattoos everywhere, strange dresses.
Germans is number 2. Same thing as Britts, but more quiet and mostly avoid real conflicts ( though this is probably their personal fear of Russians after WW2 failure). Girls looks too manly.
French. Many of them IRL are Algerian migrants, can be loud, but don't create real problems. Number 3. Some girls are nice.
Italians. Norm people, can't say something bad about them. Many their girls looks nice. Number 4.
Americans. Eat strange food, but don't create problems for another people. Young girls looks nice.
Russians. Don't like them, but this is just internal competition, for our culture it's norm. IRL they are one of best tourists ever, hosts like them very much and this is really strange ( i don't have illusions about our people, we are quite fiendish and dangerous creatures). Though our cold perfectionists behaviour create big butthurt to other tourists, many of these drunkards really hate us.
