Don't be nervous. Just don't take things too hard, and don't clown around. Act professional, don't walk on the grass at Baymont, and if you smoke, pay attention to where it's allowed.
Seriously, it's easy to get tweaked at some of the little quirks, but they are there for a reason. If you are easily bent out of shape, or clown around with no regard for anyone or anything else, this may not be your ideal career path
