I think for some people they're still a habit. In the days of Jared, they really loaded on the fresh veggies, the bread was fresh-baked and good, and the meats were quality and tasty.
Last time I went their "whole grain" option had some lousy ingredients (I've gotten so I can taste it), the vegetable's could've been put on with tweezers and the meats were the things I'd never purchase at a deli counter.
What are they thinking? It's taking awhile, but it does seem a lot of people have given up on them.
Back in HS my son was addicted to Subway. Now he wouldn’t THINK of eating their food. Maybe it’s a teen thing. Even the smallest of towns have a Subway and it’s a place for kids to hang out. I know when we moved to a tiny town, the churches had their teen bible studies at SW.
