I'm not sure how you get to the takeaway that a bartender job will "cease to exist" if a bartender is paid a living wage? There's clearly a market demand for, in this case, alcoholic drinks in a movie theater. Labor prices are seeing upward pressure. Seems to me that if you got rid of the bartender because they cost too much, you wouldn't have a bar at your movie theater anymore.
Sure, you could talk about robotics replacing low-wage workers, and in some instances that may happen, but you're also now dealing with needing to have a robotics tech available during the Spiderman rush at your movie theater where the machine that makes the drinks is a core part of the draw. So I'm skeptical of the economic argument there as it is -- you're going to replace one or two bartenders making a living wage of $20-25/hr with a robotics tech who makes the same or less?
The challenge is that it can be incredibly difficult. I never regret going, but it can be hard to motivate knowing how hard that 15 minutes will be. I can barely walk afterwards. That's unfortunately a tough sell for most people despite its benefits and I find an excuse to avoid it more than I'd like to admit.
