Measuring fluids with seconds: I, for one, live in a house with water pressure that's not totally consistent from day to day. So much for accuracy.
Coffee: Is this ethical? All for a few more ounces of coffee? Brew your own if you're that desperate...
Some of the others I think are solutions in search of a problem, but I admit that's subjective and won't discuss it here.
Also, from the HN Guidelines:
If the original title begins with a number or number + gratuitous
adjective, we'd appreciate it if you'd crop it. E.g. translate
"10 Ways To Do X" to "How To Do X," and "14 Amazing Ys" to "Ys."
"The compound that gives spicy food its kick is called capsaicin and has been used for over 9,000 years in Native American cultures to relieve painful headaches."
"used for over 9,000 years"
Also, the frying pan trick unnecessarily forces you to wash a pan later. Preheat the oven for a couple of minutes at 350F, leave the pizza right on the rack for 5 minutes, enjoy. Some pizza tastes better the second time this way.
If you want to get more for your buck at Dunkin' Donuts, go when they are about to close and ask for donuts and bagels. Most likely, if the people working are even remotely nice, you'll get a ton more than you ordered. The donuts and bagels get thrown away and most decent humans feel bad and try to give away as many as they can.
Iff you keep your ear on top of the bowl maybe. (Or just buy earphones.) Your guests will rather appreciate external-powered speakers.
There's nothing more annoying then someone wasting water like that.
But I guess the pizza part may not be so common. ;)
I use kitchen shears (kitchen name for scissors, only used for food stuff and washed like knives) frequently. I haven't tried it for pizza, though!
Also, I didn't know I was supposed to keep the plastic things in my shirts. I thought collars are straightened with starch.
