banana flies

Word to the wise: if you leave a banana peel in your waste paper bin, you're going to attract fruit flies.

In 2005, I worked at a really crummy restaurant.  There was a soda fountain that always (except for the 20 minutes or so right after you cleaned it) had fruit flies around it.  I could never figure it out.  Soda pop doesn't have fruit in it.  Maybe they were soda pop flies.  But since when do soda pop flies exist?  Nobody ever tells me when new bugs come into existence.  I'm sick of it.
