How do you pump when you work at a restaurant?

Im going insane my pump schedule is awful right now. Im a manager at a restaurant and getting away to pump when your the only one in charge and its super crazy is becoming impossible. Right now im an hour late to pump and technically my next pump is in 30 mins now.

I feel bad for walking away cause I literally got a promotion while on leave. GM went to a different store and im next in line.

This is my first kid and my days off have been rough. Im answering phone calls im answering emails im filling out reports and my baby is in my arms. Thank God his a good boy. Im 10 week pp and im a just enough er. Im worried my supply is gonna tank.

Im so overwhelmed. What do you guys do?
