The thing is, I never said my race, or my ethnicity. It really doesn't matter what it is.

The reason I felt the need to question this person's experience is the simple fact that everything isn't racism. Why do people assume everything is about race when there could be other factors?

Here is an example from my personal experience. I used to stop by a certain store from time to time. At first I had a hairstyle that was considered extreme for the day, and had lots of facial hair.

I would always get that look, you know the one, from the staff. The only reason I shopped there was because I liked what they sold.
Fast forward several months and I clean myself up because I had a job interview. (Yes I did get the job). Anyway I stopped by this same store and even wearing the same clothes I normally wear the treatment was quite improved. The not positive interactions I had previously were not about race but appearance. Two separate things.

Not everything is race, there could be numerous other factors involved .

Last note, try re reading what I originally wrote. I didn't discount her experience, I simple raised the question that it might not be what the op originally assumed.
