I liked the work environment and the people that I worked with. I also liked the flexibility with hours.
What I wish was different
There's not really anything that I would change, I love my job.
I would say that it pays to show up on time, be a hard worker, and be a reliable employee. Even if you think it is just a summer job to make money, you never know if you will end up needing to keep that job for a little while after graduation. These things make you stand out among your coworkers and increase your changes of being promoted within the company.
