Would you recommend I let the GI bill go to waste?
No, but I would recommend you think about doing something that would actually advance your career.
Since you are fresh out of school, I assume you aren't going to ULM because you plan on holding your full time job while going to school. That was the only acceptable reason to get and MBA from ULM.
I still don't know what you need an MBA for, as the "beverage industry" is mostly bartenders and product reps, neither of which require a college degree, much less an MBA. I assume you aren't going into corporate sourcing or financing, as a ULM MBA would do no good in that either.
How long do you have until your GI bill expires?
Are you just getting an MBA because it's the golden ticket to making a lot of money? From someone who has a lot of friends with MBA's, it's really just a golden ticket to unemployment due to overqualification.
Why are you so connected to ULM? Why is that degree going to be the best for your career?
