Story-reply bookings

A nail studio posts "two slots free tomorrow" to its story, gets thirty replies saying "me", and answers four of them before the day is over.

This template answers all thirty in seconds. Anyone who replies to a story with a claim word gets the slot details and a question about which time they want; anyone who replies with a question about a design or a price gets that answered instead. The gap between posting a free slot and filling it stops being a function of who happens to be holding the phone.
