Folks, if you have an issue with a particular volunteer, you do have some recourse to get that particular volunteer to "play nice".
First, figure out who is that volunteer's "boss". Inspector being a problem? Ask for the LRI. Referee? See that ref in the yellow shirt. Field reset? Supervisor. Lead Queue. FTA. If all else fails, track down the regional director and see if he can help track down the volunteer coordinator. State your complaint clearly and calmly. The lead or VC can then get the volunteer's side of the story and move them as appropriate/possible. (Or come back to you and explain--a little more professionally--why the volunteer isn't playing nice. I seem to remember an incident years ago where a team left a cart out of their pit in a hazardous area. Safety judges caused the team some consternation by removing their cart to an out-of-the-way area but returned it with a bit of a warning when the team asked about it.)
Second, I believe Pit Admin routinely carries incident reporting forms. If you can't find the appropriate person(s) to talk to, ask for one, fill it out, and I'm pretty sure that someone will be in contact.
If you've got a lot of stuff to bring in and set up, you might consider investing in a rolling tote rack, with locking wheels. That might make life a LOT easier in terms of moving things around (particularly when moving them to put floor/robot in). More wheels = more maneuverability/easier moving, ya know. A quick look at McMaster shows items of that nature ranging from $200 to $1K or so, depending on model, construction, and how many addons you opt for. AndyMark also sells
some material that can be used to build a custom unit, though that might be a bit more expensive and take some careful planning. (Trust me, that sort of stuff can hold a lot of weight. Just check the bolts once in a while.)
Food for thought, as well: How many regional champions do you see that take an hour to set up their pit/need the load-in time as setup time?
