Dev : Every user in your organisation requires their own username and password...

User: Why?

Dev: Because if everyone uses one account, every note, product, message etc made by all the user's will be saved to that one account and confuse the he'll out of everyone using it when they can't find their 'own' information they made/captured/downloaded.
We just need the user emails.

User:We can't give you all the user emails just use one account ....
(The reason for not providing us the emails is purely cause it would require user to do work and that's out of the question)

Dev: Uhm ok, but this is not what you want, and *interrupts*

User: It is what we want, do it like that everyone will understand and it will make the system easier.

*Two weeks later*

User: Why is there only one account? Why doesn't everybody have their own account? This is not what we wanted.

... The shit you have to deal with when you are on holiday ...
