Someone "could," sure, but bigger question is will they. There's five effects IIRC--I think it's a stretch calling them shows--and each lasts less than a minute. Sit there for an hour, you'll see each a couple times (maybe not the Nautilus). I don't see a whole lot of repeatability. Contrast with, say, the Grand Society Orchestra, who play new songs every set ... or the 6 hours of continuous new shows at the AC. If you're not drinking and/or enjoying the company of friends, I think anyone would get very bored very quickly.
Also, with the smaller bar, the shows often feel more localized to tables throughout the bar. When any guest orders an Uh Oaa in Anaheim, it's a big deal, because 80% of the bar sees it. Here, you'll notice the lights flicker, but when the show is focused across the room, not as big a deal.
Once the novelty of a first visit wears off (and even then), can't see anyone just sitting there watching the same canned effects for 3 hours straight.
