The toilets at my school are very, very, thorough with autoflushing to the point that they often flush before, during, and immediately after your business, but for some reason once you've wiped you have to manually flush the paper. SO MUCH WATER WASTED
Technically it's more sanitary since people aren't touching handles to flush right after touching themselves. It's also more water conservative because someone couldn't hold the handle down for a long time to be sure it flushes, the toilet only uses exactly as much water as it's supposed to.
Yeah, the toilet at my workplace has a tendency to "spit", though it isn't an automatic toilet, thankfully. I despise automatic toilets, I have NEVER seen one that works. The only reason people have them is because of people screaming about how unhealthy touching a toilet handle is. Nevermind that you should still be washing your hands afterwards(i.e. clearing yourself of whatever you might have picked up).
