at work pumping

Annie
I need some advice about pumping. I have never pumped outside of my home so today was the first time at work. A female colleague was nice enough to offer me her office so I can pump however I feel it's an inconvenience since I would need her to step out 3 times a day. The office has glass door so I have to hide behind a screen. I pumped twice cuz I felt uncomfortable. This is the corner space I was using...I sit facing the wall so no one can peek through
Did anyone pump at their cubicle? If so how do you manage? I wish there was another spot for me to pump....
