Towards the tail end of graduate school, while I was finishing my thesis and job hunting, I started working full time at a regional bank as a teller. They placed me in one of those branch units in a grocery store and although it paid okay for the difficulty of the job, I never felt it paid enough for the customer service aggravation it entailed. People understandably get really irksome when it comes to their money, and have a tendency to take it out on the messenger when they discover they can't manage their business very well.
