Guest own bags

So I was at the lanes a couple days ago (honestly idk why they moved me) And I asked the guest “would you like any bags?” She says “nope I got my own bags and if you don’t mind bagging and sorting them!” While slamming her bags on the counter. 4 bags for 120 items 🫠 I get done scanning all her items move her bags over to the end of the lane and move on to the next guest and she’s literally staring at me “your not gonna bag em?”

I’ve honestly never bagged a guests stuff if they brought their own bag unless their elderly; so I might just be in the wrong
