Pumping at work

Dear mummies, please share your experience on how you pump at work? FTM here, returning back to work in 2 weeks time. I am working as a front line staff in healthcare. Superior noted that I need to pump while on the job, however I feel bad that I need to leave the counter for 30mins each time when I need to pump. And also.. After washing my pump parts, how do I dry them? Should I wipe it with a cloth? Currently I let it air dry openly on the table at home.
