Denny's review: service, insight manager and waitress

I was charged 4.89 for 2 small chicken tenders and 4.99 for a small plate of Mac and cheese for my toddler which is outrageous. No one could explain the menu and the manger says well I don't know what to tell you that's the price. Staff was horrible and the manager was even worse. I will never eat at Denny's again. Tables were nasty and staff acted as if they didn't want to be at work what is this place
