In the department of “when not to blow bubbles”

Blowing bubbles while getting your hair cut is, apparently, a bad idea. Tiny clips of hair linger in the air, carried by all sort of turbulance taking place within the barbershop, and seem particularly attracted to the surface area presented by a bubble.

By the time I “popped” the bubble and had the gum back in my mouth, it was coated with a fine layer of hair.
