Dealer Comments On Your Play -- What Do You Do?

[BigBluffer]

1/2 NL - I'm in late position in seat 1 (next to dealer). Two limpers to me and I raise to $20. All fold and as the dealer is pushing the pot to me he says "Bet 20 to win 7. Nice play." It was clearly in a condescending tone, probably just loud enough for me to hear.

Personally, I think this was WAY over the line. To me, the dealer's job is to run the game smoothly, not to editorialize. Leave that to Gabe Kaplan.

I haven't said anything to him, but I haven't tipped him since then (maybe half a dozen pots). Obviously it's eating at me since this happened 2-3 weeks ago. What, if anything, should I have done/said at the time? Thoughts and comments welcomed.
