For some reason the corner my cubicle is in doesn't have heat blowing (or in our hot summers, AC). I just bought a tiny space heater for under $20 and I am happy. Our president is always hot so our office is more often cold, but you can always wear more clothes or have a little heater. And in the summer I have a small fan that was less than $10. Of course my mom is not allowed to have a heater and had to get approval to have an office fan, so I guess I am lucky.
