First you have to search for a parking space.
Next after the parking lot experience, your search for a desk will be pretty much fruitless so you work in a break area.
Then when you have to go you have to search for an open stall.
Three hours at a ballpark is manageable but 8 hours of trying to find a usable toilet is utter craziness and then to have your manager ask where were you I see you were away from your computer for 20 minutes.
