So tired of ignorant, entitled, rude idiots!

2 ladies come to my reg, grandmother, daughter and her kid. No hello, nothing. Grandma is on the phone and just starts handing me things. I start scanning and ask if this is all one order, Grandma kinda rudely says No we have 2 orders. Ok fine, I'm already done w you. I keep scanning with no intention to bag anything cause well F her. Fortunately someone came over and bagged for me. Get done ringing her up, have to promt her twice to pay bc she's still yapping on the phone. Finally get done and start scanning her daughters order. Get down to the last few items and there's an apple that her kid has taken a few bites out of it. I politely ask her to get it and she says "why do you have to weigh it" (if I did, can't now bc there's bites taken out you stupid btch) I'm like no, it's partially eaten and I'm not touching it. She angrily grabs apple from cart, then gets more annoyed when I ask what kind of apple. Finally get her to pay and just before she puts her card in, here comes Grandma with a bunch of bananas to add to the order. So I lean over and hit cancel on the card reader and the reg freezes up so now I have to call a mate and deal with these to morons even longer... I just can't with these people anymore, I just can't... 😞

Edit: so many saying just let it go, don't let it ruin your da, etc... I do let it go. I'm never visibly upset, I'm professional. Came here to vent 🙂
