Just wanted to give a heads up that I may be slow to non-existent until after the holidays.

Put simply, I work customer support and take the calls where people are asking for a supervisor. So my day is filled with people asking for the impossible and then yelling at me or calling me names when I say no, it's not happening. My past week has been very stressful, and it's likely to get even worse as the holidays grow closer and it's just difficult to tag when feeling like this.
