Daily Routine Disrupted

Every morning I walk into work and make the same coffee order for the old man in his 70s who comes in at exactly 8 AM. Today, I was feeling off, maybe a little too caffeinated myself from gulping my extra-strong espresso shot to start the day. So, I messed up his order. Instead of his usual medium roast with cream and sugar, I accidentally made it a dark roast black coffee. He was surprised when he tasted it but didn't complain, he even gave me an approving nod like maybe he secretly enjoyed the change. Now I'm wondering if there's something deeper going on with my daily routine, or if I just need to get more sleep.
