Inappropriate serving temperature, overfilling the glass, and drinking wine fom plastic/styrofoam cups rank right up there... No, I don't think these are any signs of snobbery, but rather of good practices aimed at maximizing the wine drinking experience.
The last wine was the 2005 Niagara Meritage. It is made by Hidden Bench Winery (Terroir Cache series) and I had it at Barberian's Steak House in Toronto.
