You never know if a movie is going to have a post-credits scene nowadays and this movie theater is going viral for how it keeps its customers know of post-credits scenes!
The theater created a designated chalkboard that lets everyone know what movie has a post-credits scene and where in the credits it actually shows up. The best part is that nothing gets spoiled as to what is in each scene so you're in the clear.
Based on the reaction to the post below, it looks like everyone would be fine if theaters across the world did something similar and it could definitely save you a bathroom trip!
