Rachel hasn't seen Michael since he made a fool of himself. Alan is still determined not to lower his standards in the restaurant. He is flabbergasted when he receives a visit from the environmental health who think that he may be the source of an outbreak of salmonella poisoning. Dan is rounding up people for the disco. Rachel decides not to go when she hears that Michael is. Nick is also having second thoughts. Carol is enjoying Alan's discomfort as the environmental health accuse him of poisoning four diners. Lisa doesn't fancy the disco in Skipdale so Mark decides that he won't go either. Dan has no luck persuading Melanie either. (thetvdb.com)
