Pumping being a waitress

Hello! I need tips on how to pump being a waitresses. I’ll be going back to work soon and

I’m scared of losing my supply. I know they legally have to give you a break but how did you do it? Stop taking tables, do a pump session and then take tables again? Or did you have someone watch your tables? I just have so many questions please help :(

PS: my shifts are usually 4-5 hours so it’s not like I have a super long day... I could just pump right before and immediately right after

Thanks in advance ladies
