"Most people have no idea how much they pay in taxes." proof?
Even though I don't write a check, my tax software it kind enough to provide me exactly how much I paid in taxes, so that I can easily calculate my EffeciveTaxRate (19%)
I don't understand it but clearly there is a market for wasting time and money to print at home.
Lets talk about it then. The resources you want to minize use of are "cost" and "time". It is faster to print a photo on my home printer than drive to a store, and pay them to do it unless I'm printing a lot. If I'm printing more than say 20 pictures, or picures of all different sizes, then it takes longer because of my paper feeder. Typically though I only want to print one or two of a picture to put in a picture frame or give to friends and family
But lets also talk cost. It's about 10c per picture in paper and another bit for the ink. That is about the same as my local shop depening on deals because their prices fluxuate and by bulk. I pretty much call it a draw there unless you catch them on a deal and buy in bulk.
That makes it about the time.
The bicycle stand at the Amsterdam train station is also impressive in its scale.
Haha this, and in my limited experiance, copenhagen.
