I have to agree with you Caz, obviously we only see a heavily edited version of the full conversations that took place so can only draw conclusions on what we see.
Yes they could focus on just renting offce space, but they might not be able to rent it all year round, so the creche is the pull that draws the customers to use their space and probably allows them to charge a higher rate as well. They made losses the first couple of years, a lot of that was from expense at fitting the place out etc but they had demonstrated it was on course to start making a profit now. Maybe it won't go onto make enough for it to be worth an investors time, but this didn't appear to be the reason the dragons declared themselve's out.
The shampoo bottles will probably do well enough Caz, i'd be surprised if it will be just boots stocking them now. Although as an idea, it's nothing great in the originality stakes but not all products have to be to make money.
