Did Lynne and 'Mantha co-ordinate their outfits for this charity vehicle wash? At first glance they are wearing the same outfit of purple halter-neck crop top and denim hotpants, but a second look shows that 'Mantha's top is more low cut than Lynne's. The dress code between them must have been denim hotpants definitely and then any purple halter-neck that you own. Let's not be too strict here.
It becomes clear that Lynne and 'Mantha did not organise this charity vehicle wash themselves. If they did, they would not have decided to go to the nearest army barracks. They would have gone to a supermarket car park instead. More cars, less tanks. No, they have signed up to an undisclosed charity to do their bit and they have been given the vehicle wash assignment. They gracefully accepted as it is certainly not the done thing to turn your nose up at charity work if you've said you'd do it. Granted, they maybe should have asked beforehand to prepare themselves, but they were undoubtedly expecting cars.
Now, do Lynne and 'Mantha still get their sponsorship money for not doing the cleaning? Have they been sponsored by members of the public or are they charging the soldiers to clean their tanks? If it is the former I suppose they could lie and say they did the washing. However if it is the latter they have to now ask the soldiers for money for washing their own tanks, lest they go back to the charity with empty pockets. What do they say? 'I'm sorry but the soldiers said they'd clean the tanks and we're far too lazy to do it ourselves. In fact we spent the whole afternoon tanning our tits.' This may be the last charity these ladies work for.
