Oh, no, I didn't mean it as it's something that has to be done, tho rereading my comment i can see where that's implied, I meant it more as:
Paying for the cab fare does not suddenly make the person you slept with a prostitute (that's what i got from OP's comment. That as soon as money was added into the equation, he's suddenly with an escort), hence "that's another story".
It isn't a must on your part to cough up cash for the other person at all, but I dunno, I feel like the least you can do is offer to pitch in if it's not gonna inconvenience you and she's not being rude about shit (in this case, it's hard to tell for me if she was); but that's a me thing. When you're raised to offer your help when you can and you lived in the not-so-nice parts of town most of your life...yeah, I tend to ask anyone that's with me if they can make it home alright and offer to help somehow if I'm able to. I understand if people can't or don't wanna do the same, tho admittedly, I sometimes forget that it's not like, the standard response, you get me?
EndeavourOS, or vanilla Arch Linux by using the Archinstall script that comes with the iso file (or the old fashioned way of following the Arch Wiki and doing it manually through the command line, if you're up for it). Personally, I'd go with Endeavour. Not only because I'm lazy, it's rock solid in general, and easy to install via the GUI installer (by comparison, the Archinstall interface is...passable, IMO), Archinstall can sometimes fail, and it can be...weird with what it leavws out (ex: I tried Archinall and XFCE once. Still had to install the user dictionaries post installation. Never found out if it still does that in the newer iso's).
Do keep in mind that Endeavour is on the light-ish side, you might need to install a couple of things to make it feel more feature complete, and also you'll have to use the terminal for updating the system, installing stuff, and maintanance--tho nothing is stopping you from grabbing Pamac of the AUR (which is set up and ready to go on first boot) and doing stuff through there instead like you did in Manjaro.
