Now that was surreal

Just back from some quick shopping at New World. Went to checkout, and conversation with young checkout operator went along these lines:

YCO: Would you happen to be David Farrar
DPF: Umm, yes. So have we met or was that a lucky guess?
YCO: No, I read your blog

It did occur to me to generalise about the probability of new world checkout operators reading political blogs, but then I recalled that yours truly spent a couple of years working at Woolworths!
