Cup of Tea?
In England, the problem with big sporting events or other nationally popular TV events is the kettle. At half time, or after the game, people pop to the kitchen and put the kettle on for a nice cup of tea. The effect when this happens across the country is a huge surge in power draw.
Supposedly the bigger problem is not the additional power draw, but actually when the draw stops, because the power stations have revved up production to supply the power and now they're producing power that has nowhere to go. Something like that anyway.
I'd argue that that's a good reason to have a filter coffee maker that just site there, but then, I've drunk the coffee and concluded that there is NO good reason to have a filter coffee maker ;-)
