Who do you contact when you have a complaint about the manager?

Maybe the main corporate office... Google Waffle House and see if the website has a headquarters and search that.

1-877-WAFFLE

I would advise calling a different location to get information. It is what I did

Thank you, my complaint is about the night mgr and 1 employee. I will contract Corp tomorrow. Thank you both.

What Liz said. Also, I'm pretty sure the Waffle Houses around here have area or district managers that cover several stores each.
