Unless he's got recirculation, the first beer out of the tap is going to be room temperature.
Im not sure of that?? I just remember visiting my brother on the job. His saying he had something to show me. We were on the other side of the house from the cooler and it came out a little warm at first, but then cooled down right away. I assumed it was due to the smallness of the line. so I got a guided tour of the system. The owner had the cooler put in first thing, so the carpenters etc. had use of it right away.
