Thank you everyone for the replies

. I realize I am worrying too much. There had been a few times where I tipped someone and nothing was said afterwards, so, I’ve been worrying that maybe they felt the tip wasn’t sufficient enough. And knowing how much nook miles a lot of people have, made me worry about all those times I’ve been tipping NMTs. I greatly appreciate everyone’s acts of kindness and generosity here, so, even if something is given to me for free, I want to be able to give something of hopefully equal value as well even if they tell me no tip is necessary. Now, when I drop NMT tips, I feel kinda awkward like I’m dropping trash.
I try to always tip depending on how big of the trade it is or what kind of trade it is even if the player is kinda rude to me; i also try to tip if a player is patient and waits for me to tt and get their order ready and/or finish a trade. The other day I tipped someone for a giveaway even though I didn’t take that much.
Yeah, I sometimes feel like there’s an awkward second or two of silence when i drop my tip.
