I've never bolted anything myself, but I suspect one sometimes has to make quite tricky choices.
For example in my local area the routes often have a few metres of easy scrambling, then a ledge, then the start of the real climbing. The first bolt is often one move off the ledge, especially for the short, thus causing complaints about the clip being too high/scary. Whereas if it were easy to reach standing on the ledge, it would also be easy to fall off just above it and hit the ledge. Either way somebody winges.
Then there was a route I was on a couple of weeks ago where the crux was off a big pedestal with the bolt at navel height, more or less guaranteeing that anybody who falls off gets seriously hurt. That is just blatantly irresponsible and stupid.
