Why do people still use ALL CAPS

It blows my mind that some data entry jobs still request ALL CAPS for entries. It’s harder to read and seems so outdated — most of us learned to type properly with lowercase letters! Anyone else frustrated by this? I just did three hours of all caps entries and my eyes are killing me?

But it’s like typing with a megaphone — everyone can hear you, but no one can understand — i totally get the frustration with ALL CAPS; I’d take legibility over volume any day. Do you think clients still prefer it for a specific reason, or is it just habit?
