That statement above is what happens when an economic sector is in a bubble that is marching toward a crash. People will shift their spending habits, which is apparent in this thread. We might eat fast food/restaurant meals once a month when it used to be once or twice a week, even more when we were in the office every day. Plus, as the population ages, which it has, fast food becomes less desirable and the market shrinks.These companies are charging too much which is lowering traffic which is making them raise prices.
Our food spending habits have shifted into the home, away from eating out. I make many things I used to buy at the grocery store because they priced themselves beyond the point I was willing to pay.
Once the buying shift happens across the market, the bubble will burst.
