Mavis

Mavis is a bartender who works at The Red Lion, a pub across the street from the school. She appears in "How's Your Father" and "The Examination" and is played by Deirdre Costello.

Profile
Mavis comes on to Mr. Brown when he visits the pub while Mr. Short administers the Lower Cambridge exam to his class, but is surprised and confused when he tells her about Josephine (who, unbeknownst to Mavis, is actually his pet cat).
