Made some minor print statement changes, and fixed a GUI bug.
Waiter break system works when there are no customers on the waitlist.

Bugs:
- Going back to working state when there are customers going around is
not working.
- No Break Case currently does not work
Finally, I fixed up the waiter breaking system and the tables full restaurant scanerio.

Now on to testing the entire simulation as a whole and seeing if the
individual components and the entire system works.
