<< I was sitting in class and I noticed a classmate rubbing his face against his visor, which was in a leather case. At first I was like, WTF? But then I realized, he was using his facial oil to treat and polish the leather of his visor case. :Q
For some reason, it was mildly troubling to watch. >>
Offer him to let you spray his face down with ether while he keeps his chin down. Collect the dripping into a jar. Let the ether evaporate and give him the jar back while saying "here's your facial oil, have fun polishing".
