I don't like when people load the cannons for me
I get that you're trying to be helpful, and it can be during naval engagements where you're on a small ship and not everyone can be on their own cannon, but usually it just annoys me.
First of all, when someone does this for me I initially assume they're trying to steal my cannon which just puts me on edge. Second, I get into a flow state whenever I'm using a cannon and can immediately pickup my own cannonball and load it myself, somebody else doing it for me saves maybe like a second at most and just isn't necessary. Also they just load round shot 100% of the time without asking me if I want to switch to another shot type, so sometimes I'm stuck using that even if I'm in range for chain shot and want to use it, so I have to tell the guy to stop loading round shot for me and now I come across as rude.
It's especially irksome when the person doing it is a sailor or surgeon or something and could be doing something way more useful instead like fixing the ship or healing people. Just my little rant
