I can't speak for Chandler's but I can speak from what I know about the industry.
Mom & Pops locations usually open with a dream and lot of energy.
You work 60-70 hours a week. You wear all the hats, accountant, purchasing agent, maintenance and operator.
Profit margins are very tight, you aint getting rich.
After a few years you're tired. Tired of hiring, training, dealing with the drama and firing personal. It becomes harder to find good people to work and follow your dream.
You come home everyday smelling like the back of the restaurant. You start to cut corners to make the preparation easier on you and to try and increase the margins.
The facility becomes dated as you're tired of constantly updated, painting and buying new furnishing etc.
Five /ten years goes by and business starts to trail off.
It's a damned hard business and I have all the respect in the world for those that make it happen, day in day out for 25-30 years. It takes a special person to live it and breath it every waking moment of their lives.
