-- Service-based Businesses who have a high-value per customer and rely on repeat business
(ie. chiropractor, med-spa, etc.)
-- Small Retail Businesses that rely primarily on walk-in traffic and repeat business and do not have massive advertising campaigns (like some franchised businesses have). The greater the degree of "passion" involved with the business' product/service, the greater the value each customer has.
(ie. bike shops, hobby shops, day spas, breweries, golf courses, entertainment facilities, etc.)
