You cannot honk your car horn at a sandwich shop after 9 PM.

The Law

In the capital city, it is explicitly against municipal code to sound a vehicle horn at any establishment where cold drinks or sandwiches are served after 9 PM. This hyper-specific noise ordinance was likely passed in the mid-20th century to curb teenagers from loitering, honking for carhop service, and disturbing the peace in quiet neighborhoods. If you want a late-night BLT, you will just have to walk inside.
