The OCR thing was my initial thought, but the angle of the picture above isn’t because I can’t use a scanner, it’s how it is!! Unless there is some new OCR technology that works at 5 degrees that I don’t know about.

You’ve hit the nail on the head though. As with so many of the examples of bad practice I come across, it’s people applying some convention they’ve seen somewhere else, because they don’t have the time or inclination to decide what is actually best. Another example I like to get off my chest every now and then is bar charts (instead of pie charts) to show percentages.
