Even if google is monitoring me, they're pretty **** at it. I don't think it's any secret that I live in London but it always picks my location as Kiev, Ukraine and apparently it thinks I have a dire need for discount plumbing services.

ETA: And I buy a ton of stuff off Amazon -- mainly cookbooks, law textbooks and sometimes garments -- but it has f*ing bizarre recommendations for me. One time I bought all my textbooks and also a few sets of shoes and underwear and it recommended an American football. The best though was when I bought about fifteen cookbooks as presents, and it recommended a home enema kit.
