I'm curious, why?
I like being recognized at the Starbucks I usually get my coffee from. Makes ordering much much easier (I always order the same 4 espressos over ice).
Depends on who you are, what reactions you've gotten, or get, in life. Notoriety and fame, or infamy, usually makes a person look at recognition as a burden, rather than a boon. I suppose it depends on what a person values. It's a curse, and a blessing at the same time. Other possible reasons, there's paranoia, social fobias, running from organized crime, hiding from government agencies, or another strong preference for privacy.
The people I do business with on a regular basis are ones I trust, otherwise, I prefer them to not remember me.
