I am currently at this job and the only thing I have to say is, this job would suit students (overseas or on a study visa) who are seeking extra income while studying.
I am only at this job because I have failed to expand my horizons on a new challenge thus far.
The work is easy and customer service is the main aim of this job.
However, you will need to be prepared to meet all types of customers, who either impact your performance positively or negatively, depending on how far you let these customers get to you. Sadly, this is the nature of this job. End of the day your job is to take whatever treatment you get from customers and accept anything your boss is tells you. Because the bottom line is you are just a number.
