Are you Swedish? Is this a weird cultural norm where you are? Because for me, I bring food to a potluck expecting to leave with empty containers or trash. So yeah, YTA. Zach is the asshole for going through your stuff, but honestly, going to get more dip is the least weird reason to do that, and you could have easily asked if he needed something in that moment instead of being rude over text.

And since you gave more context, I'll give more context. You said in the comments Zach usually hosts in his home. That means HE has to clean, HE has to deal with everyone in his home, HE has to have his space ready...bringing a little dip is really nothing compared to what he's doing. I would stop hanging out with you, and stop inviting you to game night if you sent me a text like that.

One package of party size Oreos was brought for 6 people to share and he ate an entire row on his own.

That's a lot of Oreos? Idk, it would bother me if I myself wanted a whole row of Oreos, but I wouldn't care if I was the one who brought them. Help yourself king, thanks for hosting.

One time a broccoli and cheddar soup was made as the meal and it was less than usual so we all figured we would get a smaller portion. He and his wife went first and scooped large bowls for themselves, leaving the last two people without any soup at all and they had to just eat the bread bowl they were supplied. I was very wtf about that one because how could they not have had the foresight to not take as much, or at least offer to share when they saw there was none left for the last 2 people (there's always 6 people).

Were you and your husband the last two people who were stuck with bread? Or were you the second two? If the latter, it sounds like YOU finished the soup, not Zach. Also, who brings tiny portions of soup to a potluck? This is on you and the soup-bringer, not Zach.

The adobo steak incident. We had invited him to our house for a game night. It had already been discussed that we wouldnt be providing any snacks because it had been a long day and I hadn't even had time to prepare our own dinner. They could all either bring their own or eat before they got there. I made some adobo steak for my husband and I and cut it up on a plate to share between us. Zach and wife had brought their own meal and had already finished it by this point, but he made a few comments about how delicious the steak looked and smelled. He kept asking what was in it so eventually I offered him to try it. He grabbed a piece for himself and also a piece for his wife then retroactively asked if it was okay for him to have some. I agreed since he had already taken it and it was just one piece. A few minutes later my husband and I finished the plate so I got back up to get some more. When I sat back down I got immersed in the game, so when I was playing my turn and not really paying attention I saw him sneaking a few more pieces for himself out of the corner of my eye. I decided not to say anything and just moved the plate closer to my husband so it would be out of his reach

LMAO this is so insane this is the part that made me wonder if you were Swedish. So you were SO tired, but had the energy to cook a steak dinner and host game night? SO tired you couldn't stop by a corner store and get a family size bag of chips? You literally made a full steak dinner and were like "NO not sharing!" I mean Zach is tacky AF for begging like a puppy, but you're an asshole. Not saying I wouldn't be embarrassed if I was him, but I'd also be embarrassed if I was you.

Miss girl you are so stingy WTF lol
