Work Step by Step
There are many reasons for a decrease in sales. Since this is a spa, one possible reason is poor customer service. After all, people are paying for the luxury of going to the spa, so they expect to be treated well. Additionally, since spas are luxuries that require extra money to afford, an economic recession would likely cause a decrease in sales for the spa. There are also many reasons for an increase in sales. One is a change in ownership. Changes in ownership could cause the spa to be more luxurious or to have better customer service, which would cause more people to come back. Additionally, if the economy got better, more people could afford to go to the spa, so economic growth could also increase spa sales.
