Quick update:
Contacted Cabelas about my experience. They are in the process of investigating the situation after I wrote and told them about my experience. They told me regardless of alcohol on my breath they had no reason to shame me like they did in front of people. So will see what happens I guess. Guess they are not allowed to blurt it out so loud that all can hear, and make me stand at the counter for 15 minutes, and keep telling me I will be right there.
