What is it that really makes "Travelling" in places like Berlin, Eastern Europe.very tedious and tiresome?

I have never been outside the good old US of A it is out of a principe I do not want to give these socialists any of our dollars. God Bless America

I'm saddened by your experiences in Prague and Berlin but I think that I understand why you feel 'left out'. I am an Englishman who visits Berlin quite often, and I have experienced the change in attitude of some of the older natives when they realise that I'm not from the USA. It was quite surprising the first time it happened to me - sullenness disappeared and smiles and offers of beer were abundant. This attitude is a direct result of the waves of Americans who visited these cities since the Second World War. I do NOT mean the soldiers who helped defeat the Nazis, but I DO mean the tourists who followed them. These people brought with them an extremely patronising and arrogant attitude along with their dollars. They tended to "demand" rather than "ask" and refused to understand why many natives could only speak a "foreign" language at them which wasn't Spanish. A refusal to eat anything but "American" food and drink or only smoke "Camels" and "Marlboro" didn't help. Unfortunately these things still happen. I have even encountered genuinely arrogant stereotypical American tourists in London and at Heathrow Airport ("which bus to get to Stratford Upon Avon and will I meet William Shakespeare?" True story!). It looks like you have been the victim of the legacy laid down by about 50 years of Americans "doing" Europe and getting stroppy when they realise that it isn't "like back home". Incidentally, some of the other answers to your question illustrate my point very well. Go back again, learn some of the language, try the local food (it's not a coincidence that you will find it hard to get a McDonalds in Berlin). Don't offer dollars everywhere. Never boast about how the USA won the war. Ask, don't Demand in hotels and restaurants. Don't attempt to compare prices with your home town. You'll find that they'll welcome you as a friend and you will want to return.

I agree with you they discriminate me there because I like to hump my donkey

I have lived in and traveled through western Europe for the last three decades and this (what you've posted) has NOT been my experience at all. I speak some French and Dutch but am only truly fluent in (American) English (as my British friends "lovingly" point out). Maybe your drinking is interfering with any possibility of having positive, enjoyable contact with locals wherever you are.
