Having no flights, and not filling growlers on everything are both pet peeves of mine, however, being a businessman myself, I completely understand why brewers would not offer either. Cigar City is my favorite local brewery, as well as my favorite overall. They offer growlers, but generally only on their year round offerings, and a handful of special releases, though none of the major releases. Of course I WISH that I could walk in there this afternoon and get a growler of Caffe Americano, but I completely understand why I can't. But hey, at least I can go down the bar and get a $2 taster or a $5 snifter pour. Flights are a little different for me. As someone who dreams of opening a bottle shop/tap room, I get why flights would not be offered. As discussed previously, glassware cost, cleaning cost, and staff time to fill so many little glasses (though I would think the time it takes to fill four 4 oz glasses wouldn't be that much more than a single 16 oz pour) would be a detractor. On the other hand, flights provide an added margin that would easily make up for those added costs. If a pint normally costs $5, that is approx. 31 cents per oz. At a conservative $6 flight cost, you would be making approx. 38 cents per oz. But then you need to consider whether or not people will drink less while buying flights vs full pours. I would say that in some situations, yes, but I suppose everyone is different. If it's a brewery I haven't been to before, I generally get a flight or two and then depending on time allowed, I'll get a full pour of my favorite from the night. If it's a brewery I go to regularly, I'll usually get a flight that includes some things I haven't had before and then imbibe with my brewery favorites. If it's a bar that offers flights, it all depends on what offerings they have. If there are a lot of different beers that I've been looking forward to trying, I'll usually get a flight or two. If there are less than 4 beers that I am looking forward to, I'll usually go for full pours.
