Nice cake... heh heh heh heh....
Could it be the low pay, harsh work conditions, and general anti-worker culture at Wal-Mart that's getting this person upset? Or could it be Wal-Mart's hiring of marginal employees, like gangbangers with, ummmm, unresolved anger issues, that is the issue here.
Mental health cutbacks, stress in schools, low wages = special cakes in the Wal-Mart washroom.
