I recall a Zee Bashew video that I can't seem to find that referenced a chart of how willing someone was to help when requested. The idea being the scale isn't from "I will actively hinder you" to "I will sell my estate to aid you" but rather from less then helpful to more helpful.

For example, if you asked some haggard clerk about a quest the scale might be:

• Critical failure, the clerk directs you to the job board for details on any job.
• Failure, the clerk may point out there specific job on the board and direct you to it.
• Success, the clerk tells you that the person who posted the job is staying somewhere in town.
• Critical success, the clerk may share a rumor they heard in addition to telling you where the poster may be staying.

Regarding a discount from a penny-pinching inn keeper, perhaps it could go:

• Critical failure, payment for the entire stay is required up front. Extending your stay is not permitted.
• Failure, They are not willing to lower their prices
• Success, they will offer a lower price if you bundle extra services like meals, drinks, and baths.
• Critical success, they will offer you the bundle rate without bundling.
