They've had cocktails for years, that's nothing new. I don't buy them, because the only time I bought a beer in a movie theater, they charged me $12. That was pre-Covid. Its probably $18 now. How do they think that charging those predatory proces is going to entice people back to the movies?
With those predatory prices, I have no moral qualms with bringing in my own. I stop at Dollar Tree on the way to the theater, buy my snacks there (they have candy in noiseless movie boxes for $1.25 instead of $8), and sneak in those and a bottle of water. I've been doing that for many years, and nobody has ever said a thing. My son walks in with a tote bag full of groceries, and nobody ever stops him.
