Anecdotally this is me. I work from home 3 days a week, 2 days in office. Pre-pandemic I ate breakfast, lunch, and sometimes dinner in the road...2.5 hour commute. Food prices have increased 10-40% at each one of those stops. Now I eat one lunch per week out to socialize. The other 5 meals that I used to eat out are groceries I buy at the store and carry in.
