Nick still has his childish imagination, and remembers to foster it everyday.
The bigger joke is that he was seemingly going to be late anyway since work started at 7:30.
Also, on another (only very slightly interesting) note, not every country has bread ties like that; some don't place clips and their bread bag just uses some bendy wire, and others have other more distinctively shaped designs.
I remember seeing an image of bread ties from around the world and different time periods... (very slightly) fascinating I know...
