Seems you just can't get away from them, people that just have to complain. Give them a free steak dinner and they're unhappy it didn't come with desert.
Even at Disneyworld (the happiest place on earth) the most commonly heard sounds are crying kids.
But I will agree that there does seem to be a little uptick of grumpy people on TOTV here recently which prompts me to ask the question, "Is it the heat or the humidity?"
