Read this as "a time and a place for fights" and thought this turned into a tree house parking lot thing already.
FWIW I love flights as a patron when they're mine (keeps me from getting stuck with ****** beer, get ticks in a larger than sample format) but hate them when i'm next in line behind flight guy, or as a bartender (dramatically more work than one beer, especially if there's a paddle involved)
My personal favorite is what places like wicked weed do - a 3oz pour of anything for one of a couple set prices ($2 or $3 i think, depending on the price of the beer) and you can do that as a flight or just 1 or two at a time. I think that's a good compromise (and, keeps people from sampling all day without buying, another pet peeve of mine)
