NPCs can be so dry and bland when they come up and you aren't prepared for them. Other NPCs often times only have the stats rolled up and their personalities are neglected. That is where a list of simple characteristics can come in handy and you can stereotype the NPC and at least give them some kind of quirk that defines them a little better. Nobody may remember the innkeeper at that one city, but they may very well remember the innkeeper that picked his nose right before he gave the players their change. Just some little things to define the NPCs and make them more real. Some can be used by players as well to spice up their character a little.

Gregory Merchant is an art dealer in Daggersford. He is well-versed in art, history, and art history, but rarely brings these subjects up other than in context of a sale.  His sales technique is very low-pressure, and he is content to let people browse his shop. There are a few small statues available, but the shop focuses on paintings of various sizes, values, and significance. He seems perpetually distracted.  Is it a ruse?
