Running an apothecary shop with Kobolds *Updated again*

You've worked hard to earn this shop. Sleepless nights looking for flowers and herbs that only bloom at night. Spending hours hanging them to dry, and grinding them up once dry enough. Through word of mouth, villagers are starting to show up at your cottage in droves. You buy a storefront but quickly decide you're going to need help. You don't trust the villagers. The secrets of your craft have taken a long time to perfect. You have no plans to share them. You take the time to find a kobold village and offer some of them to work with you for rocks, shiny pieces, and Moss. The kobolds are perfect, not interested enough in your craft to learn it, but enough that you can explain to them which herbs you need. However, the kobolds are a little too small to stock the store, and you can't keep having them climb shelves, breaking things. Later that night, you bring the kobolds to your cottage. You make a potion for them, giving all of them cups of the concoction. Moments later, the kobolds drop their cups, crashing into one another as they hit the floor.
