wine connoisseur bluff

When you're in a restaurant and you're asked the taste the wine, not knowing really what you are tasting for, so you sniff the wine before you drink it, drink and nod in acceptance... whilst you find the whole formality unnecessary and pretentious

Waitor comes over and shows the bottle label to diner.

Diner: yeah... that's the one I ordered, what do you want me to say?

Waitor pours about 3 sips of liquid in the glass and "Shows you the glass"

Diner sips it.... the whole table is now in suspense

Diner nods in acceptance and everyone in proximity has a sigh of relief and ponders on the 2 minutes wasted on wine tasting and the diner for his wine connoisseur bluff
