I've (20M, first-gen Filipino immigrant) been working as a Petco sales associate for my first job for three weeks now. Last night, I had to ring up a middle-aged white lady and her partner (husband?) who were buying over $550 of dog/cat food and toys. The lady was visibly stressed with whoever she was calling on her phone. In the middle of my ringing her up, I politely ask her, "What (animals) are you getting all this stuff for?" This bitch then decided to lash out at me, saying that "You have no right to ask her about her purchase/reasoning and that you should just ring me up!" She, of course, demands to see my manager. Not having experienced a karen first-hand before and thus not knowing what to do, I calmly try to apologize and continue ringing her up, but she still demands to see my manager, clearly wanting to get me in trouble. I catch her muttering to her phone, "This motherfucker is asking me why I'm buying all this," then her partner laughs. At the end of ringing her up, she goes over to the next cashier, asks if he's the manager, and repeats her bullshit. Second cashier does page my assistant manager (also a middle-aged white lady) to the front. The assistant manager approaches, I immediately tell her I was simply trying to ask what animals she has, and the bitch once more repeats her bullshit. Assistant manager tells her that asking people about their pets is LITERALLY ONE THING A PET STORE EMPLOYEE IS SUPPOSED TO DO. Only then does the customer calm down, and she admits she's been having a bad week (makes sense considering how she's been acting during her call).

Bitch, everyone has their bad weeks, but don't fucking take your bad week out on some random-ass store employee making $12/hr just trying to do his job. And you could've just politely told me that you're not comfortable with talking right now, thank you, instead of going on an entire tirade trying to get me in trouble for one of the simplest, most expected pet store questions.

Races and ages mentioned because I'm wondering if either of those have to do with my experience last night.

This morning I topped off the water to my aquarium. Before this, all of my ember tetras were okay. I decided to pour the water into the internal filter to avoid stirring up my new sand, which pouring into the usual spot did. My guess is that it made the current too strong for a few minutes. The rest of my ember tetras made it out well and alive, but after the topping off I saw one of them against the wall of the tank struggling to swim. I decided to isolate it with my critter keeper inside the tank for what I thought would be a few hours. However, less than an hour after I isolated it, it died... I'm thinking the current slammed it against something too hard, or that it fatally stressed it out. What do y'all think happened?

(I didn't get any photos for evidence)

EDIT: I checked the water parameters and everything is good.

EDIT 2: I also conditioned the water before adding it.
