Sharjah and Dubai need a clear boundary
Many people live in one emirate and work in another. A person can spend the day in Dubai and return to Sharjah in the evening. A location estimate can place the same person in different emirates at different times of day.
For example, a Sharjah restaurant with delivery only in Sharjah may receive daytime visits from people at work in Dubai. Those visitors cannot order at lunchtime.
Your brief can set delivery hours that match the times when your audience is in your area. This works because the campaign reaches people when they can use your service, and the report becomes easier to read.
