My work pays for my food.
Also, I’m busy working, so I don’t actually have time to cook my lunch, so it’s either eating something frozen, which is unhealthy and gets old, or get delivery, so that $30 for a meal.
Also, my commute is a fifteen minute walk, because I absolutely optimized for not having to drive anywhere. The only benefit to wfh was seeing my kid more often, but that had its own caveats because it is hugely distracting. So, it’s cheaper and more productive for me to be in the office.
The only reason I’d want to work from home was if I wasn’t actually working, and my bet is many people see it as exactly that.
