I may have a few quirks myself; touching my face persistently is not one of the few. Especially in huge wiping gestures, like how you would wipe your face after a facial wash, except that you’re really smearing facial oil over the already oily surface. I mean, that could only serve as a means to evenly distribute facial oil, to achieve a homogeneous spread or what have you. It may be a subconscious gesture, seeing the many perpetrators unaware of this social quirk. And the hands resume normal routines. They go on to shake other people’s hands, to email on their blackberrys or touchscreen phones. Some phones have enough smear on them; you could scrape it off and it would suffice frying an egg. Oh yeah, the railings on public transports as well. Thumbs up.
