This module will allow you to pay several open point of sale orders at the same time.

The principal order will return the other orders amount and the other orders will be payed with this amount.

@legalsylvain I'm answering because I'm at the origin of that PR
You're in a bar, you want to pay someone else's drink who is not on your table... ;-)
You are in a store with your family, you want to pay your family's ticket but you want to do it with single payment (check or credit card). At the end, you have 2 tickets and one payment.
For us, it will be used in a vertical use case but we wanted to propose the functionality to the community

That makes sense ! coud you add the uses case in the description.rst file. That's allways interesting to understand why a module has been developped concretely.

thanks !
