no where to pump at work 😓

i just started as a server at Applebee's and my 11 week old son is ebf. i have a few bags at home that will get him through a couple of days but to keep my supply where it is ill need to pump . i usually get engorged in 4-5hrs if i dont pump or feed my son. i told my boss ill need to pump but he said there is literally no place to pump that doesn't have a camera besides the bathroom. Plus being a server its rare u get to sit down to eat so me takin 10 or 15mins to pump will already be hard enough ..what should i do?! i live in Pennsylvania
