It does make sense but very strange of course about the police.
Mind you it does say the following on the gov site and nhs site this
Stay at home
Only go outside for food, health reasons or work (but only if you cannot work from home)
If you go out, stay 2 metres (6ft) away from other people at all times
Wash your hands as soon as you get home
Do not meet others, even friends or family.
You can spread the virus even if you don’t have symptoms.
So the visiting friends or family the lady must of had plenty of traffic her way. If one is to provie incalls to take the risk of one or two clients you might aswel hike your price for one or two bookings that cover the high risques. So less traffice in order to make your targets.
