Posted by Sa lahat ng may buhok (kahit pito o walo lang ang buhok n’yo):
Huwag galitin ang inyong barbero habang kayo ay ginugupitan niya ng buhok. Lalong-lalo na kapag hawak niya ang gunting o labaha. Baka matapyas ang inyong tenga (o ilong) nang “hindi” sinasadya.

hey amerlon, if you are gonna give a series of advice you should not keep it only to the tagalo speaking people, you know? lol!
I’ll interpret it just for you then: Don’t make your your barber angry while receiving a haircut, especially if he’s holding the scissors or the razor. Or your ears (or nose) can be clipped “accidentally”.
