The lifestyle of a Unit Manager is not sustainable on a long term basis... 24/7/365. You are promised opportunities to advance, exceed written and oral goal, and then someone else is given the role. Promotions are political, no ifs, ands or buts. Amazingly, I was offered three seperate promotions after I gave my notice, including one on my last day. Waffle House is your life if you expect to succeed here. If you are ok with that, then you can make it. But just know going in that most folks don't think the juice is worth the squeeze.
