What About (a) Bob?

When I was in Saigon last month I went to a hair salon, which I found via a YouTube video. It's got something like four floors, and these computer-simulated images of what you would look like in various hairstyles.

I didn't need the simulators because I knew what I wanted, which was just a trim.

I was shown to my seat, and three people stepped forward to assist me, not including the stylist. They were like my little ladies in waiting.
One presented herself as the interpreter and asked what sort of haircut I wanted.

"I just want a trim."

Blank stare.

"My hair is bobbed, so I want it the same, just shorter."

Blank stare.

"I want a bob."

The self-appointed interpreter gets in a huddle with the stylist. The other ladies in waiting also join in. My hair is often referenced via gestures, with a few stroking of my locks. But no one seems to agree on what is needed.

The interpreter exits the huddle and turns to me to ask me a question.

"Who's Bob?"
