If I'm in a public area - too bad so sad for me. Even if I'm not in a pubic area, it's the danger of trying to record something in an uncontrolled environment.
I've be out in the backyard trying to record foley sound effects for a Nazi soldier walking through a forest in 1942 and I get some fecking parakeet squawking all over it. Certainly the parakeet is a douche too - but what are ya gunna do?
Plus you can keep that stuff for the gag reel.
