BAE SYSTEMS Theory #1
The cafeteria is kept a lot colder than many employees find comfortable over the summer at the NCA facility. This is due to the massive number of employees at the location. If every 1st shift employee were to take their lunch at the regular time, there would not be enough seats to accommodate everyone. A side effect of this cafeteria setting is so employees do not take a longer lunch break than the company desires. The cold drives employees back to the comfort of their desks.
