There can be lots of reasons people don't click on what you want
- Rude - Intentionally avoiding your requests because they can
- Vindictive - Intentionally avoiding your requests because of some real or imagined offense you cause them
- Blind (some can overlap with speed reason)
- Can't find XYZ building
- Browser doesn't load properly/quickly so they guess what is under a hand
- Requested name is hard to read. More precisely takes too long to read, especially when you get in a rythm
- Speed
- Clicking anything they can
- In a rhythm and reading requests takes too long
- Mistake - normally good but occasionally misses
For me city name requests are painful to read if your trying to be quick. Not in terms of the time to read but in terms that everyone does it different. You get codes are the front of names and back of names, some put H after B and M and some don't, some use separators and some don't, you also get word requests, some requests are out of date (requesting a culture building that they don't have anymore).
For me, the biggest contributor to me messing up someones request is a poorly written request in the town name. For those I visit often I eventually learn their quirks, for those I visit less often it comes down to luck.
