Karen's mother, Natalie, arrives unexpectedly and straight away starts putting pressure on her daughter to find a man and get married. In an impulsive attempt to get her mother off her back, Karen tells her that she is in love with - and engaged to - TJ. TJ agrees to play along to help Karen out, and his performance has Natalie Hansson fooled. The rest of the staff are amazed to hear the news, and it soon gets back to TJ's new girlfriend, Julie, who doesn't take it very well. In fact, she smashes a vase on her 'two-timing' boyfriend's head. Everyone else is preoccupied by the latest corporate headache - a temperamental old push-bike they have to use for deliveries.
