Identify the real reason for Scottish visits
A prepared drink may suit a lunchtime break, a shopping trip or a quick visit after training. Açaí bowls might involve different purchase occasions and preparation time. Aberdeen's Union Street should be studied on its own terms rather than used to predict behaviour in Glasgow's retail districts or Edinburgh's tourist streets. A familiar city name tells an operator little about who would return for a smoothie during an ordinary working week.
Observe a candidate frontage in weekday mornings, lunchtime and evenings as well as weekends. Record whether passers-by have time to stop, how close competitors are and whether the customer can wait comfortably for preparation. Do not treat a nearby gym or university as proof of conversion. A few short customer interviews may help separate occasional interest from recurring purchasing habits, but site-specific projections still need independent validation.
