Two reasons to bypass:
1- You're using a generator
2- You have no ground BUT trust the source. Recently had this experience at one of our favorite CG's. The outlet was bad, but since we knew the weather would be clear with no chance of lightening, and the area isn't known for brown outs or spikes, we bypassed the EMS. The outlet was replaced by camp staff during the week.
I would add #3 which i have done on occasion, if the voltage is low, I will use some electrical items, 120 volt light bulb lamps, etc. or cheap toasters etc. and even the smaller/cheaper AC that I installed in my bed room for just these occasions. IIRC when in bypass mode it retains the protection against spikes.
