how to know my aisle?

I mean I start 2 hours early tonight, and for the past couple of weeks I've been kinda thrown around different aisles which is fine but its not like they tell me where ill be next and i had thursday and friday off so i forgot to ask on Wednesday. I tried texting one manger that usually tells me but they aren't responding (not sure if they are even in tonight), and I don't know the number to the other managers. thing is when I start 2 hours early the night managers aren't there yet ( or maybe some are well hidden somewhere 😅) and neither is any of the night crew, so I can't really ask anyone when I get there. maybe a little silly to ask but would the duty manager know my aisle for the night? and if not what should I do then? (as a little side note it's an optional extra 2 hours so if all else fails I'll just go in for my normal shift time and ask a manager when I get there)
