Wines by the glass in a classier fashion.?

Okay, I guess this isn’t so much a question as it is a suggestion for all the restaurant and bar managers out there.

Most restaurants pour their wines by the glass into a glass or small carafe at the bar and then bring the wine to the diner’s table.

A few of the really classy places I have been to in Montreal and Quebec City would bring the bottle to the table, show me the label, then give me a sample pour to ensure the wine is okay before filling my glass.

It’s a little extra effort for the server, but I really can’t see how an establishment could go wrong doing this!
