You can do things like; touching fabrics in HK stores. I did that. Because I did not know that touching their wares is a 'crime'. No English. No touch. No business. Just leave! They don't want your money....
Never, never, ever forget to validate your railway tickets in Berlin. That is another 'crime' that you will be getting into. As the 'officer' who held me and my family off the subway train said in a form of a question, "Do you know that, not validating your ticket is a 'criminal' offense? Can you guess what my answer was? Your guess is as good as mine.
I have warned you many times about Cairo. And will continue warning you that an Egyptian pound is worth a fortune to most "business-minded" locals. If you are travelling by train from Cairo to Alexandria and you seem to forget which of the trains you should be taking, behold! - do not ask anyone going around near the trains posing as a dispatcher because if you do ask, which I did, you will pay a price for sure. Not a pound, not two - it's 10 Egyptian pounds. You don't want that to happen, do you? So, get on the train and ask other passengers. Most of them will give you an honest and friendly answer...for free. And, that is one of the things I am going to do on my next visit to Egypt.
Does things like these happen to you while travelling? Tell us, let's learn from your experience.
