The pie chart compares the percentages of the number and type of ratings about customer service that were taken from 100 guests in 2005 and 2010 at the Parkway Hotel.
Although the percentage of people who were satisfied with customer service decreased, overall customer service quality improved significantly because a huge number of people rated it as excellent or good.
The percentage of people who rated customer service as excellent was just 5% in 2005. Five years later, the proportion widened to just around one-third. Also, the difference between rates in 2005 and 2010 in the proportion of customers who marked customer service as good was 25% (14% and below 40%, respectively). Clearly, the overall percentage of positive ranks grew by around 40%.
Between 2005 and 2010, the percentage of guests who were satisfied with customer service decreased dramatically, from around half to one fifth. In addition, the percentage of negative ranks like poop or very poor was 21% and 15%, respectively. Fortunately, there was a decrease in those trends to 12% and just 4% in order.
