i've seen racism all too often,though not targeted at me,the worst case so far was when i was traveling with my brother,in Warsaw(poland)i was in an egyptian kebap shop within the train station at 4am(i had to take a train at 5:30)when a guy came in, and got a kebap,he saw me and my brother were white and asumed we'd support him so he threw the kebap on the vendor and started lashing on him telling him to go home to his country etc.needless to say we didn't support him but chased him out instead,and stayed with the vendor to console him,after a few minutes he showed up again with a police officer(or maybe the station's security i couldn't tell)and claimed he was attacked,the security guard,didn't care that there were witnesses and blamed the vendor aswel,long story short,he made the vendor apoligise,which he wasnt eager to do of course
