I noticed that too, but was not sure what to make of it.
I’ve had bosses who were overly friendly with everyone, but it was just their personality. didn’t bother me.
I’ve also had bosses who were generous and gave really, nice gifts at Christmas as well as taking out the entire staff once a month to celebrate everyone’s b’day who had one that month.
Once time, my company had a Christmas party and since many of us lived far from work (myself 50 miles) he offered us hotel rooms at company’s cost so we wouldn’t have to drive home drunk.
All that said, if Mr. Cain gave gifts or booked hotel rooms for someone INNOCENTLY..I would not be surprised whatsoever.
