Bartending is a young man's job, the opportunity to be a 50 year old, male bartender are few and far between. Further, the job is not good for the soul, it may be fine for a young, single guy but the hours, the booze and generally toxic environment of working in a bar/restaurant is not good for an adult. Let's also not forget that most service jobs don't include health insurance and other benefits that while may not seem like much at 30 they are super important later in life.
