Would you call out a fake?

I have a buddy at work who likes to tell tall tales and everyone knows it. We've had discussions about Rolex since he often sees me on TRF. According to him he's had several over the years... I don't really mind him fibbing BUT today he came over and showed me his new 16610. One look and it was obvious it was a bad fake. When he took it off for me to hold it was really apparent how fake it was - weight, clasp, dial font, date numbers were not crisp. I simply congratulated him and said he had a nice watch. No need to call him out or burst his bubble. He even went as far as to say Ben Bridge authenticated it.

It got me thinking... Would you point out the fake or let it be?
