To stop bags of cable ties emptying themselves all over the place....
Don't cut the top of the bag (or rip it open with your teeth).
Instead, you just cut a slit horizontally, half way down the bag, so you just grab one and it pulls out from the middle. No fumbling, no mess.
Can't remember who told me this one, and it took me ages to remember to do it, but its a goody.
EDIT: It wasn't THAT good!! Can someone delete the double post, pls?
