+# Introduction
+
+Your friend Yaʻqūb works the counter at the busiest deli in town, slicing, weighing, and wrapping orders for a never-ending line of hungry customers.
+To keep things moving, each customer takes a numbered ticket when they arrive.
+
+When it’s time to call the next person, Yaʻqūb reads their number out loud, always in full English words to make sure everyone hears it clearly.
