"They'll have reason to listen to you if you wind up rich and famous and a known expert."
She hands over a thick notebook, full of lots of detailed information. "Just read the first fifteen pages for now, the rest of it's meant for reference."
The questions are mostly memorized facts. What does this pill do, what color are the feverfew pills, how many aspirin should one take and how often, and so on.
Aya gets most of it right, although she mixes up a couple numbers and hesitates on some of the other questions.
"Pretty good. But if you're not sure about something, look it up. Consider it at least as bad to sell someone the wrong pill than to sell them none at all. I think I've given you more than enough work for today, though. I'll see you tomorrow."
"Yes. I'm already renting the place, after all. And like I said: I can sleep anywhere. I'd appreciate if you keep bringing me meals, though."
"I can do that. Should I expect to take over the rent at the boarding house after the duration of the first payment is up?"
"I hadn't decided whether to increase your pay to account for that, or to simply keep paying for it myself. The former is probably neater, in case you want to move or something. Remind me when that happens."
Aya writes that down. "I will. Anything else for today? Can I take the notes to study from while I cook?"
"Sure. Just don't damage 'em or new paper will come from your pay. And I'll see you tomorrow."
Aya nods, takes the notes, sleeps, and brings breakfast and undamaged notes in the morning.
Steel eats breakfast, gives her the shop key, wishes her luck, and tries to locate the families she gave medicine to the other day and see how they're doing. If she can't figure out where they live, she'll go to the slave market and pretend to be considering the offerings, instead.
She walks around the market, pretending to consider various people at no clear pattern and applying her tattoo-removing technique to them. Hopefully the proprietor won't kick her out for loitering before she gets a majority of them. It might help that she gave him a significant amount of money to free Aya, a few days ago.
Is business any better today than it was yesterday?
Aya has done quite a business compared to yesterday while Steel's been gone - for values of "business" that involve honoring the promises of free product - maybe people just like the native-looking shopkeeper more. Aya can spread that rumor, sure.
When Aya comes back later in the day, she waits across the street for half an hour and counts how many people go in compared to how many pass by. Looking at the numbers at the end of the day, does it seem like people are just more likely to come in when Aya's at the storefront?
Aya gets fewer "curious" and more "actually want things" - so, no, but more relevantly interested people come in.
Does the shop's reputation seem to be improving after a week of this? Any loyal customers who keep coming back?
Aspirin in particular with its obvious and frequently useful effect is popular. One lady is hooked on the allergy suppressant, and a small family who seem to be primarily motivated by spite against their previous herbseller-of-choice come back with a list of things they want her to stock or come up with replacements for.
Over the course of that week Steel slowly increases the prices from 'at cost,' to 'just a bit cheaper than most other herbsellers,' makes an assembly line for production of aspirin, and looks into mixing up a stronger painkiller or even an anesthetic. She advises the allergy-suppressant lady that taking more than two per day will hurt her throat. She manages to stock or replace all but one of the spiteful family's list of things.
Then she makes a big batch of everything that's been selling well and pays Aya two weeks' wages in advance, telling her that she'll be visiting the markets in some of those other cities and if anyone wants white pills, they should come back in a couple of weeks.
