Just a thought, any inputs?
Sometimes (most of the time?), commercial kegs come with a hand pump. People pump air into the keg to get the beer to flow. Usually, it's overdone and the beer foams all over the place. For forced carbing, usually it's because the lines to make it portable are too short. I take longer lines, and just coil them up with a zip tie and don't let anybody touch the co2 tank!
One other thing I've seen is operator error. People want to take just a little beer so they only open the tap a little bit. That causes tons of foaming. Kinda like a garden hose- pinch the end a little and you get much greater force coming out.
