Seen crickets, horse sperm, quite a bit actually (including a snake). I've seen the goldfish. We had one problem though. Was a hot day (hit 102, which is dang hot in Washington). Was delivering a non commit route (takes almost an hour just to get to the first stop, let alone rest of the route). Gold fish sat in package car all day (was at the end of the peninsula). Say it this way, fish were all dead. Customer wasn't mad at all surprisingly. She understood it's quite a drive out (if we drove directly there, would be about 90 minutes from the center to her door). So would've cost about an hour down time (30 minutes each way from beginning of route to her door) just to drop one package.
