I wouldn't want to sit down and have my lunch with a screaming bat right across from me.But that's not likely to happen because bats are smart enough to avoid things like cave walls,and humans.

I love watching bats on nature programs,they are truly amazing.
Although between them they can build a pile of crap as tall as a small building!
If it came to a choice of going out for a drink with a horseshoe nose bat or Olly Murs,the bat would win hands down.It can sing just as well,and it's a lot less embarrassing to be seen with in public.
