Is this what passes as a conversation in this relationship now? George and Lynne really are having problems. Lynne is making loaded statements to try and sucker George in to complimenting her and George is falling for it. Also, is Lynne insinuating that she's not content in her marriage? Actually, if you look again George has double bluffed Lynne with his last statement. To her, he is complimenting her, but in fact he is calling her a prostitute.
George and Lynne have come to buy a purse for Lynne. Lynne has chosen this shop because of the sale that is on. We know the sale involves a reduction, but we don't know if it is 7% off or that these purses are only 7% of retail price. This must be some sort of factory outlet.
The dowdy sales assistant is eavesdropping on George and Lynne's conversation and has failed to spot the burglar who is pilfering a selection of bags. This woman is a professional burglar so wears the required outfit of a black and white stripy top. She should be easy to spot but she's quick on her feet. By the time George and Lynne have got to the cash register, she has already ran off and is next door in a greengrocers.
