1st public feeding experience?

I was advised to take our 6 week old baby to the E R. I told my hubby to prep the baby's bag. While I was in the crowded waiting area, our baby started to wake up, and as usual he cried a little. I gave him a pacifier and eventually he pushed it out and it landed on the floor. So I tried to calm him but it was not enough. I reached for a bottle but it was not there. I took my baby to a single stall restroom and it was of course, it's dirty. So I walked down the empty hallway into the corner and started to feed. I had a pull over blouse on but I had everything covered up neatly. Then an employee walk by and she wanted to see the baby. I told her that he was feeding and she said "You better go in the restroom like white people do'. BTW, I'm Black and that comment ticked me off. So I walked back into the waiting room and asked the registrar if they called our names. She asked why did I have him dd that way with a blanket and I told her; then she frowned and said I should buy a shawl specifically for feeding for situations like that. The baby chit chat died and I took a seat. A lady sitting across asked to see the baby. Once again, I got the awkward look from people sitting across from me. My son latches great and I did not touch my at all in the waiting area. No one could see my because my chest was covered well. I did not plan on going to the E.R. that day but the feedback was mainly negative about feeding in public. I don't take our baby anywhere unless it is necessary. My question is: Has anyone encountered similar experiences?
