Do two sets of jumper cables (not chained, but simultaneously connected to both batteries) charge a dead battery faster than one set? My boss seems to think so, but it seems to me like if you complete the circuit, the charge would be the same.
At first I misread your question to be whether two batteries would charge it faster than one and spent some time looking at whether it would be better to have the batteries connected in series or parallel (series would be better, but the higher voltage might be dangerous).
Your question is simpler. Having two sets of jumper cables would definitely not charge the dead battery significantly faster. It would technically lower the resistance between the two batteries, which would theoretically tend to speed the charging, but the resistance of some beefy wires is already incredibly low (very near zero) and the effect would certainly be negligible. Having good contact with the terminals would be much more likely to make a difference, but even that isn't worth worrying about.

yes [virtual fist pump]! I knew it!
