It could literally be someone’s special free of allergens lunch, that can’t just be replaced. Also, tbh I wouldn’t want to eat something a random person made, who I don’t know and don’t know their hygiene etc. or what’s in the food.

Also they don't know their money situation. Just because they work at a well paying job doesn't mean they're only providing for themselves. They might not be able to afford to buy a new lunch every time someone eats their's.

Edit: apparently I need to make it more clear. What I meant was the person bringing their lunch can't afford to keep buying lunches if someone steals their's.
