I do it everyday before I go to work because I am just too Lazy to get up earlier to apply my make-up.
I mean I sit in the train to work +- 35 min everyday so it is a perfect way to kill time.
HOWEVER I do not do this in Japan.
I am a "gaijin" so people allready watch my moves closer so I make sure that I don't want to attrack extra attention by doing stuff like that.
