I used to get loads of grief when I lived on Edgware Rd in London although most of it was in the shops when some rip off twat who had the prices in arabic numbers tried to overcharge me not realising I knew arabic numbers then.

Or from the Nation of Islam idiots who would yell Infidel at me when they had thier silly little stalls and campaigns against the vote for London mayor.

Never had any major problems anywhere else, except a few odd looks when i speak in my english accent in the East End of Glasgow!
