Dealers making comments about bettor

[betgo]

A couple of times in 1/2 NL this has happened and I don't think it's a good idea.

One time someone raised to 15 UTG. The dealer said "he never raises." No one called.

Another time, I value bet a dangerous looking board on the river with a big hand but nowhere near the nuts. The dealer laughed and said "poker face", refering to me. I assume this is because I had a real classic poker face, which I have naturally, and not because I was showing anything. Again no one called.
