Quick answer: Ask how the company turns your offer and location into a real plan. Ask what's included, what's on you, and how they handle changes. Clear answers matter more than big promises.
What exactly is included?
Ask about staff, the sign, design, printing, setup, schedule, and reporting. Don't assume the word 'campaign' covers all of it.
How do they check the location?
Ask who checks the approach, access, safety, and local rules. Get the agreed plan in writing.
How are the people trained?
Ask about training, dress code, breaks, weather plans, and who's in charge during the shift.
What can they honestly measure?
Ask what signals your business can track, like calls or visits. Don't accept promises that treat attention and sales as the same thing.
