Flo, Mary and Annabel were at the bottom of the pecking order in the checking room, and spent most of their time reacting to Ivy and Edna's latest dramas. When Ivy left her husband Jack after catching him entertaining his fancy piece Cheryl Crowther, Flo joked that Ivy had worn him out. Later that day, Flo initiated an argument with Ivy by insinuating that she was after Alan Howard. Edna then joined in, and ended up bearing the brunt of Ivy's anger when Ivy pushed her into a rail, knocking it over just as their boss John Fitzpatrick walked in.
