Arthur needed to prioritize making the potions since the raw materials he had weren't exactly stable. They would deteriorate the longer they were kept and lose their effects.
This was a common thing with many fresh ingredients and they needed to be processed to be kept for a longer time. It was a limitation that took some equipment and work to overcome, but for the start it was fine to use them as it is.
"Welcome, how may I help you?" At the potion shop, a young man greeted Arthur.
He looked to be eighteen or nineteen and was clearly not the owner of the shop.
"I would like to buy some small potion vials as well as wish to use the potioneer's workbench," Arthur replied.
"While I can sell the potion vials, I cannot personally give you the permission to use the workbench. I'll have to ask Master about it first." The young man replied.
It was confirmed from his words that the young man was just an assistant at the shop.
