So there could be a way to earn money like working HG shifts or completing quests. money could be spent in the gas station. Here are some ideas for items you could get there:
Chocolate bar: When used, it will give a Quentin a short-speed boost.
Oil Bucket: A bucket filled with oil, it will function like the paint can, but dirty AIs will take longer to swill off.
Sedatives: Put it in a cup, an AI might drink it and become tired, and will need to sleep for a small window.
Strong UV bulb: You will be able to put this limited-use bulb inside of a flashlight. Instead of functioning normally, it will emit sporadic bursts of light, blinding residents for a few seconds, and possibly scaring any strange night wanderers.
Gas canisters: They can be used on a fireplace or stove. They will smoke the area and cause residents to look for the nearest fire extinguisher and spend time putting it out.
