Low Voltage @ Duplex Outlet

I am just curious. Today on an unrelated job, the occupant in an assisted living facility, asked me to check a duplex outlet because his cell phone would not charge there. I measured 68 volts and can't wrap my brain around how this could be. I verified my meter by checking other outlets and all were solid 124 volts. This is not my issue to repair, but just how can you get approx half voltage? 73 and still learning,

Digital meter I bet? Phantom voltage can make it read all over the place. I've seen in the 40's to the 70's.

When you read a strange voltage..... plug something in like a floor lamp and check again. The lamp will eliminate the phantom voltage.

Thanks. All replies make sense. Yes, it was a digital Fluke. I have experienced phantom voltage before, but had forgotten.
