Restaurants are overrated?

1. Eating at home saves money.  If someone is looking to save up money for traveling, buying a car/house, emergency fund, or whatever it is, eating out less is often the easiest fix.
   
2. Eating at a restaurant does not necessarily save time.  You save time from prepping and cooking.  But you lose time from the commute there, the commute back, waiting for the food, waiting for the check, and sometimes even waiting for a seat.
   
3. Eating at home allows you to track macros and calories accurately.  While popular chains have info posted, most restaurants in general don't.  With how commonplace the use of butter and oil is in kitchens, it's very easy to underestimate calories when eyeballing.   If your fitness and body composition are priority, dining at a restaurant should be limited.
   
4. Lastly, it depends on what food you order.  Many restaurants have foods that do use uncommon or "high-end" ingredients and/or require a lot of skill to prepare.  But many entrees on menus are also things that are cheap to make, easy to make and use common ingredients.  It doesn't make sense to go to a restaurant just to order things you could make yourself at home.
   
5. At home, you can control the temperature, lighting, music that's playing, what's on television.  And there are no screaming kids.

And there are no screaming kids

Subjective of course.  But I'll make my case:

To shop on a full stomach, or just to get rid of the hunger, sooner rather than later?

When sadolite is out of food in the house, then goes to a restaurant, 'then goes to the store,

Is this so that he doesn't buy unnecessary food, as people sometimes do when hungry,

Or simply because he wants his hunger sated sooner, rather than later?
