People you will meet on the job:

The I hate engineers guy.

In a lot of your internships and new jobs you are going to encounter some technicians or blue-collar guys that hate engineers. Their feelings are often the result of two different things. First they have encountered young, cocky engineers who think they know everything. Second many of these people are also intimidated by people who have gone to college.

There is nothing you can do about the second part. But there is a lot to gain on the first part. To begin with, do not be cocky. Realize that these people know far more about their work than you do. Defer to them. Try to learn from them. You will endear yourself to these people, NOT BY SHOWING THEM HOW MUCH YOU KNOW, but rather by asking them lots of questions about what they know. Be a sponge and get them showing you the ropes. These guys might hate engineers, but they will like you.

TBL: Do your part to give engineers a good name.
