Vanilla? Where's the waitress? I only eat Rocky Road.

Our reading
An editorial interpretation.
The speaker rejects vanilla and asks for the waitress, insisting on one particular flavor instead. The short questions and firm 'only' make a small preference sound nonnegotiable. The comic effect comes from the importance placed on getting an ordinary order exactly right.
