Just so you know, there's an app called Atom Tickets. I use it and it's great. It allows you to buy your ticket through the app, for a small fee of course, but then you get to just walk inside and have the ticket tearer person scan a QR code on your phone. Skips the line, ticket window and(if the theater has assigned seating) lets you pick your seat aswell. Do this at my local AMC all the time. Just make sure to buy the ticket a little before you get there so the app has time to process.
If you have android: https://play.google.com/store/apps/details?id=org.gamatech.androidclient.app
You do! If you're anything like me (poor, broke, unemployed, disheveled), you can always download the Atom Tickets app. They do a little promotion thing where your first ticket is free, which is how I managed to see Don't Breathe.
