Just why

Had a lady who was literally my second customer of the shift come up to the register, put back an item for her already but then gets to the mascara she’s holding in her hands so I can’t ring it up obviously as she’s just deciding in line for some reason, she opens up the packaging of the mascara in front of me, takes it out, opens it, looks at it and goes “that’s too dry for me” and hands me the mascara and packaging and says she’s not getting it and her reasoning for not buying it after I just stood there for a minute dumbfounded wondering if I should like ask my manager if I should even ring this lady up because of this entitlement at this point she says it’s cause she’d just go out to her car and have to come back in and return it anyways. I cannot believe some of these people, this perfectly good mascara had to go in the goddamn damaged and be throw away because I watched her open it in front of me and it’s so annoying to see the waste people don’t even care at all. Had another lady asked me to double bag literally a singular can of coke and a bag of small chips earlier, if you’re using it for trash bags fine but most of these people are just straight up throwing away these bags they don’t need this many of because they just want em for the small walk to their car when we have carts you can take out at my store
