"Poor memory.  I was topside during the Crusades.  One of those Knights Templar hit me over the head with a relic.  Long ago I could remember every mission I was sent on and the details.  Now, I can barely remember my client's regular drinks.  It's part of why I bought this bar.  Forgetting a drink order isn't near as dangerous as forgetting a mission half way through."  He point at the human's glass.  "Want something else?  I have some human food around too if you're nostalgic.  Bring it in from some of the 'heaven' areas.  Sometimes the dead, demigods, and humanoid demons like to order some sort of meat-on-bread thing called a 'hamburger'.  No idea why it's called that."
