The best sandwich shop in my town is the deli at the grocery store. They are less concerned about skimping on ingredients because it's more important to entice you in and get you spending money in the aisles.

For $8 or $9 they will stuff a footlong sub so full they can barely fold it over. And it's generally fresher ingredients than you'd find in a Subway

There’s a Jewish deli near me that gives me a full meal for ~15USD and the sandwich they give you is PACKED with meat and incredible bread. It’s glorious. There’s no chance I’d go to Subway over that.

Also, subways business model is predatory to their franchisees and employees.
