We are having an unusual heat wave right now in the southwest states. We are barely out of winter.
Panera has an "unlimited sip" club, so I can stop in any location and get a free coffee, tea, or fountain drink. One free drink every two hours. That's why it's my office space of choice. The real issue is some locations (seemingly dependent on the homeless population in the area) do not have electrical outlets available for customers, so I have to choose my Panera carefully if I'm living on the road.
