17. But, This Is Average, DAILY Number

Your description does not sound like you do it daily.
I worked for 43 years. I knew almost nobody over 30 that dined out for lunch every day.
And, I worked a lot in reasonably urban settings, though not all.
I saw people eating leftovers, sandwiches or microwave lunches in lunch rooms or conference rooms or at their desk all the time. When not traveling, I went home for a sandwich or salad 3 or 4 times a week. (Yes, I lived only 9 miles of low traffic volume road from work.)
I question this being a daily average. It just seems too high.
So, does the parking number, as there are MILLIONS of people who work at places with the own parking lot. Cost of parking there is zero.
So, I vet what you're saying, but there are conditions that have to be met by essentially everybody at your number.
The "everybody" is a sticking point.
