Well I selected 1, 3, and 5. Some other selections may play a small part but I think that those three are the main culprits.
As for as eating out is concerned, I travel a lot and eat out a lot but nothing compares to a good home cooked meal. My dining out is paid for by the company but I still prefer good home cooking. As for burgers, Whoppers are ok. No burger from McDonalds appeal to me. Hardies's has some that are decent. We don't have them here but Double cheeseburgers with Jalapeno's from Whataburger down south are about my favorite. Sonic double jalapeno cheeseburgers are a close second. All these new gourmet burger joints are just overpriced examples of the same fast food stuff. 5 Guys, In and Out, Backyard burgers, all are just overpriced versions of the same old thing. Red Robin has about as good as I've eaten away from home.
All that being said, NONE of them even come remotely close to a hand patted thick fresh ground beef burger cooked on my own grill. Forget the cost. If you eat just to satisfy your hunger, then the others will do. If you eat to truly enjoy the experience, nothing compares to a home grilled burger.
