Generally I always decide with anyone im there what to get so we can try and share stuff.

For instance i know i never manage to finish my fries so i Never will get any...or we just get one portion of fries which is usually enough for the whole group...because surely none of us will take cold fries that get rather soggy home..not like you can properly reheat those.. just order less and share lmao.

I feel like this communication with friends, family and partners is quite normal especially with stuff getting just more and more expensive

Here in germany you even get the option to get a "bandit plate" in many restaurants especially for this purpose so one person can just choose to take food from others plates and share...they just give you an empty plate so you can share.

Like legit i sometimes choose to get this because my meds supress my appetite a bunch so im usually fine with taking a bit from everyone. Saves everyone money and hassle lmao...and everyone usually leaves a bunch anyway because holy hell restaurants sometimes overfill plates and stuff is just so filling.

Communication. It isn't like you need to nudge people anywhere. You can just communicate...
