Group Chat Cab Booking (part 1/3 of group chatbots)

I believe in chatbots, ..they are definitely on the rise. In this example, I've taken a normal conversation amongst friends who're at the same party and need to leave on time. The host who also happens to be the chat group admin books uber for them.

* I'm thinking of having a utility chatbot that covers three areas:
booking a cab, creating an event & ordering food..all set in a group chat scenario. The plan is to figure out interactions for x number of users.
