Saw a documentary about Subway, apparently they are one of the worst! You gotta give them so much money from your earnings that there’s barely anything left for yourself, but subway dngaf if you don’t even make enough. There’s probably subreddits about opening a subway franchise. Also, what’s your background? Would probably help heaps if you worked in a place like that before, ideally as a manager so you have/had insights into the paperwork. Making a Sammie ain’t enough to run a business.
