Yes. There is a wrong way and a correct way to sit on a milk crate.
I understand that we're on set for long periods of time and chairs, unless you're one of the special few with a designated seat at video village, can be hard to find. So what do you do when you have a strong urge to get off your feet? You sit on anything that seems stable enough.
For grips, that often means an apple box or an unused dolly. For everyone else, it's whatever they find, which often happens to be a milk crate. They're usually lying around set, probably by a distro box, containing stingers or miscellaneous gak*. And when stood up on its side, can be a suitable place to rest your butt for a bit.
While I usually don't have a problem with people treating our storage containers as lounge furniture (provided, of course, they get the hell out of my way when I need something), I take issue when they use the wrong milk crate.
Yup. You read that right. You can't just sit on any ol' milk crate.
For the love of gummy bears and unicorn farts, PICK A MILK CRATE WITH A STEEL BAND.
They look like this:
And like this:
And like these:
Note the steel band wrapped around the top of the crate. THOSE ARE THE ONES YOU SHOULD SIT ON.
The ones without the steel band, like this one?:
Yeah, they may look a lot like the ones with the band, and a milk crate's a milk crate so what's the big diff, amirite??
The steel band, as simple and inconspicuous as it may seem, is there to strengthen the crate and help keep it's shape. If you sit on a "regular", all plastic one, your fat (or skinny, it makes no difference) ass will distort the crate, causing the sides to bulge out and the top to cave down. Which may not be a big deal to most people, but when your distro cart's packed down to the millimeter and you depend on the crates stacking neatly on top of each other for easy transport only to realize you can't because some asshole decided to sit on your gear and you're now trying to fit a square peg into a round hole, you bet your last cookie it's a big deal!
Now, I'm not saying that a steel banded crate will never bend. When it comes to a well seasoned Teamster, anything can happen. But while a steel banded crate will sometimes bend, an unbanded one will always bend, no matter who you are.**
And if, and only if, there are no banded crates available and you're just dying for a seat and the only option left is a regular, plastic, easily distorted crate? Please at least have the common sense to sit on the back side (as opposed to the open side) where your weight will have a less of a chance of fucking it up.
* The accessories that usually accompany a distro box: splitters, gang boxes, lunch boxes, etc.
** Unless you're a small, child actor. In which case, you should be either on set or in the schoolroom; not sitting on a milk crate next to a 1200 amp distro box.
