I travel with the following portable office in a tote in the car:
* Hole punch
* 3-hole punch
* stapler & staples
* pencil sharpener (mechanical AND electrical)
* pens & pencils (of course)
* portable shredder (the chad bin is the tote!)
* package of 50 document protectors
and the piece de resistance
* Extra 1" and 2" 3-ring binders!

I haven't been into it since I first packed it a year ago, but the last time I needed to make more space in the car, I didn't even think about this bin. It's staying in the car! :^0
Edit: Forgot the scissors and tape! Except that they came out the first trip and have never gone back in.
Oh, yes. I am currently a "Field Service Technician." The last support job I had, I was a "Customer Service Engineer." Not much difference between the two; the current job is actually more technically demanding.
