I was a barista all through college and for 2 years following graduation while getting research experience. I had no idea this was a stereotype but it works--coffee is important. Everyday that I continue to work in service, my soul thins a little, which is impressive considering I don't believe in souls. Nevertheless, if you have no research experience you probably will not be very competitive. So since research is essentially a second job (typically unpaid and very time costly) especially if you become a P.I., coffee is the right industry for attaining this delicate balance. I worked as a supervisor at starbucks for 7 years and recently switched to a small local roastery (for my mental health and way better tips!).
