Worst working conditions you have written code in?
stonemetal: Industrial automation controls programming at a tire factory in Georgia.  It was 90 degrees outside and you're in a large room with row after row of tire ovens that run above a few hundred degrees. We had machines with thermal sensors set to fault out at 120 and ac units on their enclosures and they still faulted regularly.   They spray the tires with lube so they don't stick to the ovens so there is a layer of  black crap on everything.  All the machines running made around 100DB of noise.  I got put on the project towards the end as it was way past due and they wanted to appear to be doing something so they decided 24hr on site was the way to go so I was working 8pm to 8am.
