Comparator in the driver

This driver is horribly embarrassing, but leaving aside its jumbledness,
why is the Comparator not sorting? I want to sort guestsByCity using the
Comparator BY_CITY.

Basically, various representations of a collection of Guest instances is
the requirement.

I do have a GuestSort class with the Comparator, but couldn't get it to
compile, so stuck it in the driver:
