I showed up at the shop to get my mane trimmed, and took notice of another customer already in the chair.
He was about 80 years old, very thin and dark, face almost like a skull, hardly a tooth in his head, and a few wisps of white hair on a mostly bald head–which, for some reason, he was having trimmed.
At the end of his haircut, of course, the near-toothless farmer grinned and paid his 50 baht, plus a generous tip.
