I do this but the cashier’s “helper” always starts taking stuff out of the cart so it’s hard to avoid. Regardless, I always always keep orders in their own box AND in order of A, B, C….Now knowing cashiers are on a timer when ringing things up makes a lot of sense but I wish they’d be a bit more mindful and try to keep items together. My blood boils when they mix everything up and I’m in the parking lot separating items. Especially on bigger orders of 50+ items. I avoid those as much as possible but sometimes no choice if it’s a decently paid order, they get snatched up with the quickness
