Almost banned from Madrona Grocery Outlet then asked by store manager if I’m transgender

Almost got banned from a Grocery Outlet for carrying a sealed essential needs bag from a local disability agency. They watched me on the camera and then said because I have such a large bag with me I must have stolen something. I was then grilled over each item in the bag. He told me he could scan the items to prove I got them off the shelf but none of them rung up. None of the items I had were items grocery outlet even carries. Never was I warned that outside bags are not allowed.

Then he asked if I was transgender and for my birth gender and told me about how he is worried his son might be trans.

I asked if I could leave and he said yes, but informed me that he could have banned me for this even though I was proven innocent.
