They say that they were partners with Minstry Ideaz but also the managers (of the shop). Partnerships require a lot of trust and many people have been screwed over by operating under a partnership.
I might be wrong but when you look at the goods in the shop, they don't seem to be the same sort of things that are sold on the Ministry Ideaz' website. They look more upmarket and of good quality.
Who knows, the current owners may have bypassed purchasing from Ministry Ideaz and this stuffed them around. Ministry Ideaz may have counted on making a profit from selling their own merchandise but the managers/partners had their own idea of what should be sold, possibly to make it more appealable to the general public. Something like that would easily cause a rift between partners who simply have a different idea about how the business should be run.
One person in the partnership thinks that their ideas are better than the others and it's a battle as to who gets their way. Someone loses for one reason or another and they feel sour about it.
If you have a partnership you have to make the contract watertight and even then there are many loopholes. Not only do you have to worry about and work at the business being a success, you've got other partners to appease as well.
