Help with automatic movie scheduler /u/Skoilarr Python Education

I’m making an automatic showtime scheduler for my job at a movie theater. I have been fighting with the scheduling logic and so far have it working almost as intended. The output my code is giving me looks like this:

Auditorium 1: Moana 2

Showtime: 10:00 AM

Showtime: 12:40 PM

Showtime: 03:20 PM

Showtime: 06:00 PM

Auditorium 2: Moana 2

Showtime: 10:45 AM

Showtime: 01:25 PM

Showtime: 04:05 PM

Showtime: 06:45 PM

Showtime: 09:25 PM

Auditorium 3: Moana 2

Showtime: 11:30 AM

Showtime: 02:10 PM

Showtime: 04:50 PM

Showtime: 07:30 PM

Showtime: 10:10 PM

Scheduling complete!

The one problem is that it isn’t scheduling another show in Aud 1 when there is still time. I don’t get how it is able to add the 9:25pm and 10:10pm but not an 8:40pm? Please help!
