The pharmacy has three cash registers, but does not have an employee who specifically works as a cashier at each one. This provides flexibility in the operation because, of the three employees that the business has, one can collect at any of the cashiers when available. By not having to leave a single person as a cashier, the cashier can focus on providing more direct customer service, refilling merchandise on the shelves, and even assisting in receiving or dispatching merchandise from the store.At the…Question 2: Muscat Auto Workshop is a vehicle service centre located in the city of Muscat, which provides vehicle maintenance/repair services.

To test this, you decide to use a natural experiment in which a chain of gas stations ("Thrifty") suddenly closed. This closure occurred between June and October of 2012, and meant that gas stations that were previous close to a Thrifty station experienced less competition than before. On the other hand, those stations that were not close to a Thrifty station did not experience any change in competition. You decide to use a differences in differences design, in which gas stations located near a Thrifty station at the start of 2012 are the treatment group and those that were not located near a Thrifty at the start of 2012 are the control group. You look at how prices change before and after the exit of Thrifty. This is plotted in the below graph, where the solid line represents the average price of stations that were…Dollar General Corporation operates deep-discount stores offering housewares, cleaning supplies, clothing, health and beauty aids, and packaged food, with most items selling for $1.
