One of the things I most love about my boyfriend is that he's very adventurous, and incredibly meticulous about researching, well, everything, but particularly new or new-to-us experiences to make sure he's getting a good deal / knows all the variables to consider when making choices / has aggregated suggestions and tips from experts and aficionados / etc. My boyfriend's researcher personality type is an aspect of his personality that I admire tremendously. But. It makes going out to dinner with him absolute torture.
Often my work day will get stacked up with conferences, errands, etc., and I'll have to go a long, long stretch between lunch and dinner, with the result that by dinner-time I'm hungry enough to wrestle and eat a bear. I'll let BF know: "I'm so hungry I'm in physical pain, so I need to eat ASAP. If you would like to go out for dinner, please choose a restaurant before I'm home or else I will eat leftovers."
Invariably, BF does want to go out but hasn't chosen something. I suggest a place. He vetoes it. I tell him to choose; he asks what I want to eat and I say I don't care just so long as we get in the car and drive, because I don't want to sit in the car with the engine idling looking at Yelp reviews for forty-five minutes. Before we lock up the apartment I make him swear up and down that he's really, truly decided, and that we will be eating in twenty minutes.
And then. We sit in the car. We idle. He says I'm hungrier than him so I have to choose. He vetoes every restaurant I can think of, and after fifteen to twenty minutes, finally, grudgingly agrees to an old standby -- then as I drive there, he's on his phone tap-tap-tapping at the Yelp app and, sure enough, before we've even gotten half a mile out of our complex, he's giving directions to some new restaurant that neither of us has tried, because he looked it up! and it has great reviews! (And to be fair, the places usually are good, but half the time, by the time we get there we're both so hungry we have pounding headaches and hunger-nausea.)
The whole time I have to grit my teeth and remind myself: "Hey, 99% of the time, being in a relationship with a novelty-oriented researcher type is the best life you can imagine! No one can turn off their whole personality just because their significant other is hungry!" But I've started keeping emergency baggies of trail mix in my glove box.
Your comment about hunger nausea reminded me of a time that I got sick, projectile sick, because my blood sugar crashed hard. It was a (very unfunny) comedy of errors. I wanted some dishes that were on sale, we stopped after the gym, and they were going to have to give a rain check. No wait! They have them! In the back. They'll find them! Then the sale price wasn't in the computer and the cashier could not get it right. At one point the dishes were bagged and the register say she owed me $67. I said, "Know what? I'll take the $67 and the dishes and get out of your hair." She almost gave it to me! On the way home I started crashing (I'm not diabetic, I run hypoglycemic) and wanted DH to pull off, but... it had just snowed hard, the roads were barely plowed, and we couldn't pull off. I tried not be to sick, but... So, all that to say, you can tell him what might happen if he doesn't make a decision. Immediately.
Mine for my DH just happened tonight. DH uses an electric razor and tends to roam around while he's shaving. If I walk past, he'll kiss me or he'll come to where I am to give me a smooch. The problem? The razor is spinning away on his cheek and I and convinced that it's only a matter of time before my long hair gets caught in the razor. To his credit, when he thinks about it, he holds the razor behind him. He doesn't always think about it, though.
