Back to spending tons of money on gas, and a stressful commute arriving in a bad mood after the commute, getting home wiped out emotionally, physically, and mentally from the commute plus the day spent dealing with the constant social drain to be around people who are not colleagues, or remotely related to the work I do. Spending money on food that I have to keep cool or worry about it being stolen. Spending money on coffee because the center coffee is gross and my own won't last long enough. To dealing with absolutely disgusting people in the bathroom. Back to having my car frequently scratched or dented by jerks who don't let anyone know they hit your car while backing into or pulling out of a spot. All that extra expense at the same time inflation is going sky high driving up the cost of everything while we know our merit increase will likely not match inflation.
I want to thank @1wsk+1ejtj0WS for perfectly encapsulating why so many of us don't want to go back to the office. There are more than enough big and small reasons that make quitting over this a real possibility for so many.
