They also have a sampler. I think there are some good tables in there and I'm planning to do a few posts about them.
ENCOUNTER TABLE - POOR QUARTER
In my campaign, 9 times out of 10, the PCs are probably in the crappy part of town anyway. Keep this chart handy and roll % based on the time of day. Most of these categories are self explanatory. It wouldn't take much work to generate a quick NPC and assign them to one of these categories. You could easily use my GM Cards to make that happen. Also my 3 word NPCs.
If you roll Category 1 (Already Occurring) the Sampler has this table as well.
