TL;DR Looking for ideas about how to tame a shrew. I will start cutting dates short if I have to but would rather find something less drastic.

This has come up a few times for me lately. I figured I'd ask for ideas about how to handle a girl exhibiting behaviors that annoy me.

The one thing I can't stand is a girl that's high strung and complains too much. I also hate being told what to do. Usually if a girl tries bossing me around, I ignore her the first couple times and do what I was going to do anyways, which works out anyways and I assume / hope that she realizes I don't need her help and stops trying to boss me around. If she continues then I'll tell her flat out that she is being a pain in the ass and to stop because she is annoying me. Sometimes I will be more subtle, but it seems this often goes over their heads.

Example of subtlety: Went on a hike with a girl last weekend. She had wanted to hike by a lake because she "liked being near water." There were no lakes a convenient distance, so we went to another hiking place. I pointed out the creek to her and told her, "There's some nice water for you."

"No, I like BIG bodies of water like lakes and rivers, not little creeks like that."

"You know, you're a really hard woman to keep happy."

She apologized and backtracked, but she was still a general pain in the ass and even that rather blunt line would have gone over the head of a lot of girls.

Another girl, last night: told me what parking spot to use, what route to take to get somewhere, then saying, "If you went the route I told you, it would have been faster." Also we tried to go to a bar, I said, "It looks closed but let me check the door" she says, "don't bother checking the door" when I do anyways and it's locked, I get "I told you so" and other bullshit.

I eventually tell her straight up that she is annoying the hell out of me and to quit nagging. She apologizes, says, "I guess that's just my personality. I will try to stop." Wound up at her place she tells me not to make noise in the kitchen because roommate (who's watching TV at high volume in her room). I grab a plastic coffee cup from the cupboard to mix a drink she makes me put it back and use a different cup.

Outside on her patio I tell her I'm going to rig an electroshock device to her and zap her anytime she nags me. She's studying psychology so I ask her for advice on how to apply principles of operant conditioning to train her better. She dodges the question, but gets the message, maybe?

We go inside to fuck, but she can't resist complaining about something else that was trivial, so I just put my clothes on and leave. (we have fucked a few times before). While I'm driving home she texts me that I left some beer behind but that she will make sure it's still there the next time I come by. I think she felt bad about pissing me off, not that that matters much.

I would really like to know some ideas on how to get chicks to modify their annoying personality traits while they're with me. What I am doing is not working.

Failing that, I may try saying, "I told you I hate being nagged. I'm taking you home. Maybe the next time we get together will be more pleasant," even if it's the middle of a date. I'd like to hear about other people's experiences with this tactic.

Side question: what to do if we're in the middle of dinner. Pay and take the food to go right there, tell her she's going home after dinner and eat as normal?

I'm an old guy and just recently started dating younger girls and a lot of millenials. Are they all like this? I don't remember this sort of shit from girls my own age. Is this a generational thing, a bitch management thing, or am I just unlucky lately?
