do you say it as kay-bin or k'bin?

Kay-bin.

It reminds me of the property manager at my first apartment, back in 1990. She spelled her name "K'ren", and I assumed it was pronounced either Karen, or kuh-Ren. Nope. It was "KAAAAYYY-WRREE-NNN", three syllables in her very southern accent. The stress was on both of the first two syllables. 😂️
