Ideally I think shally should add something like mandazi to her business because not everyone likes samosa but almost everybody likes mandazi..... and she might also start selling tea for that matter and will be shocked on how people love home made tea too. Secondly if shally knows how to make different types of snacks like mahamri, (small maandazis) bhajia, samosas, chapatis etc she can open up an account on social media, be it Instagram or even TikTok or even Facebook and advertise her work there doing small videos of her preparing the snacks and she's be awed by how many people she'll reach.
