George and Lynne have gone to see Vicky. Lynne sees a man painting the house and assumes that he must be Vicky's new handyman. Vicky brings him a snack and he then slaps her on the bottom. Someone says he is a bit too handy.
Vicky, a friend of George and Lynne's, has employed a man to paint her mock tudor house pink. Even though the house is quite big, he has decided to just use a brush. This may be because he is being paid by the hour and he is trying to swindle poor Vicky out of her money or because the outside of the house is pebble dash, which can really only be painted well with a brush. Vicky's handyman has not parked his car in the drive as you would expect. He must live locally and just walked round with his brush and pot.
Vicky emerges from the house with a tray of treats. She has brought her handyman an espresso coffee, a piece of celery and some houmous to dip it in. It's not a substantial meal but it's more used as an appreciation of his hard work.
George, for it is he who has made the exclamation from the driveway, believes that the handyman has slapped Vicky's bottom in order to show his appreciation for both the snack and Vicky's appearance. He has misread the situation however. Vicky had wanted to converse with her handyman during his break about the leaky tap in the bathroom. She has gone to sit down but the handyman has stopped her so that she doesn't get pink paint on her clothes. Being of foreign descent, he is not able to quickly get out a 'Watch Out!' in English so has had to resort to more primitive forms of warnings.
