Late parents

Man I’ve been in this field for eight years and only once have i found a NF that doesn’t show up late 😅. This current job is more than one family and every single day I’m leaving work 5-10 minutes late. Which I get idk t a lot but ugh it’s so annoying. They expect me to be here and have everything set up right at 9, so why can’t they just be on time. Sometimes they send a text and something they don’t. And even when they do text they never ask if it’s okay. They just simply say I’m going to be late. Also, do you charge for this? It’s only ever like 5-10 minutes but it’s every day
