The crew, helping customers, the communication between yourself and your co-workers. Of course the pay was good too.
What I wish was different
I wish I had better performance, had I been in a much higher position to influence knowledge & skills, but most of all, if I had stayed with the crew a bit longer with better health.
Advice
Don't let others down, always be on time, help the people as best as you can, and show enthusiasm towards your co-workers.
