A real enquiry, handled on WhatsApp while the plumber's on the tools. Replies, gets a photo, estimates on the plumber's own prices, books the slot — and the final price still gets the plumber's one-tap approval.
This is a simulation using a sample plumber's pricing (call-out £60, blocked sink £90–£160). The real assistant runs on the plumber's own rules and their existing WhatsApp number. No prices are ever invented — anything outside the rules, or any big job, routes straight to the plumber.
