The staff are cautioned to be on their best behaviour for the visit of regional manager, Miss Grimes - an extremely large formidable woman, who's stopping by to inspect the latest developments at the Rio. Ray spots this as his opportunity to get the manager's position at a new London bingo hall, so he's determined things will run smoothly. Following a mix-up with paperwork, Miss Grimes gets the impression Ray is lusting after her and wants to meet in the cellar! Ray is left with a dilemma: should he meet his match made in hell or tell the truth and loose his chance at the new job? Martin has tried everything to get over Christine, so he thinks visiting a therapist will help to overcome his feelings. But her ways are a little eccentric, specially since she's a therapist-cum-florist.
