Pros
Working as a graveyard shift attendant at Circle K stations gives experience in multiple fields that have longevity as cornerstones of the service industry. It is at once a mechanical and social experience. A job that can give you challenges in both those facets can be fulfilling, if certain variables are met on both sides of the employment transaction.
Cons
There are constant ethical quandaries that are inevitable in this position. Customer service, especially when it's available in the deep hours of the night, comes with risks to one's very safety, and your employers will avoid discussing such issues until it's too late. The Circle K franchise specifically has a known poor track record with considering first the safety of their employees, and due to the nature of such a low paying position, they will not hesitate to terminate you under any circumstance that could introduce legal fees. The employers also have certain expectations about both how one goes about their work, and how they treat certain classes of customer, which are not particularly fair or concerned with respect for any party that is not essential to the operation of the business as a whole. In a graveyard role be prepared for attacks on your decision making skills from both sides of the counter, and work with your own longevity in mind. It can be a perilous assignment in which split decisions make large differences, day by day and week by week.
