The Restaurant Turnaround Playbook

The CONTROL 90 Method for Owners who want profits, Standards and Guests Who Return

Your restaurant may be busy, well known, and still be losing control.

Food cost drifts. Labor schedules are built from habit. Managers explain problems instead of closing them. Standards exist on paper but are replaced by shortcuts during service. Guests pay, leave politely, and never return.

The Restaurant Turnaround Playbook was written for the independent restaurant owner who knows something is wrong but cannot get a clear answer.

Chef David Arnold places the same questions, inspections, evidence requirements, controls, and 90-day sequence he uses in restaurant turnarounds directly into the owner’s hands.

Using the CONTROL 90 method, you will learn how to:

• contain immediate financial, operational, and food-safety risks
• uncover the real causes of food-cost and labor variance
• control purchasing, receiving, inventory, recipes, yields, and portions
• rebuild kitchen production, guest service, and management accountability
• recognize the guest who never complains—and may never return
• replace unofficial workarounds with dependable operating systems
• create weekly scorecards and a practical 30-, 60-, and 90-day recovery plan

This is not a hospitality memoir or a collection of restaurant theories. It is a working intervention system for owners who need to stop the losses, restore the standards, protect the guest, and earn the return.

The check has closed. The relationship should not.

Every Shift Sells

Every guest interaction either builds value—or quietly gives it away.

In hospitality, sales is not a department. It happens at the host stand, in the kitchen, behind the bar, at the front desk, during service recovery, inside a proposal, and in every decision a leader makes before the doors open.

Every Shift Sells shows restaurant, hotel, catering, and food-service teams how to grow revenue without turning service into pressure or relying on discounts and giveaways. Drawing on more than 25 years in hospitality and 14 years of international consulting, David Arnold uses real stories, practical tools, and operating controls to explain how trust, product knowledge, timing, recovery, and disciplined leadership turn ordinary shifts into stronger commercial results.

Readers will learn how to:

• Recognize the sales responsibility in every hospitality role
• Make confident recommendations that improve the guest experience and average check
• Recover problems without automatically giving away the house
• Align sales promises with operational capacity
• Coach employees through focused pre-shifts and practical corrections
• Measure revenue alongside trust, safety, teamwork, and repeat business
• Implement the complete system through a structured 90-day rollout

This is not a book about scripts, pressure, or sales tricks. It is a practical operating system for owners, managers, chefs, servers, bartenders, front-office teams, and hospitality professionals who want stronger revenue, better guest loyalty, and an operation that consistently keeps its promises.

Every shift sells. Make yours worth repeating.

Modern Water Treatment Systems is a practical technical handbook for technicians, system designers, operators, consultants, and experienced water-treatment professionals who need a broader command of the industry.

The book begins with residential fundamentals, then scales the same principles into commercial, industrial, membrane, deionization, and high-purity applications. It explains not only what equipment does, but why treatment processes work, what operating conditions they require, how they fail, and how performance should be verified.

Readers will find detailed guidance on water chemistry, sampling, filtration, activated carbon, oxidation, catalytic media, softening, ion exchange, reverse osmosis, disinfection, deionization, EDI, hydraulics, pumps, storage, controls, commissioning, preventive maintenance, troubleshooting, safety, and documentation.

Technician-level calculations, system-design examples, advanced notes, treatment-train diagrams, field checklists, and From the Field commentary connect accepted technical principles with real operating experience.
