For instance, I'm on Jury Duty in the US this week. Kinda a freebie but I still have to call in and input my "ID" number, birthday, and zip code before entering phone tree options to hear my summons status. So I saved a contact in my phone for the jury hotline with the main number, my Id number, birthday, zip code, and menu option numbers all separated by a comma. Now when I dial using the saved contact, it will automatically enter everything in and I don't have to fumble around and spend unneeded time to hear if I have to report.
This can easily be adapted for any automated phone system that you call frequently although you'll have the best results when you have to enter in a long account number like at a bank.

That monkey. That monkey fucking knows it was put in downloads but doesn't want to give you the satisfaction of knowing. Bitch
