I get a break for lunch in my, somewhat illegal, 8.5 hour work day. Typically I try to wait to take it as long as I can so that it better breaks up the day. Wait too long however and the mind starts to consider forgoing the break in exchange for an early departure home. That debate is currently ongoing in my mind as I consider if I can survive another two and a half hours without food or whether I should cave.
Gripping stuff, I know.
