I agree with OP. You’re a person to. Question the one who is walking on top of you no matter how awkward the corner might be. In my case it was a very civil and fair environment, I was not wronged in the end.

I always get very nervous when standing in a line. I’ve been cut before multiple times and didn’t say anything. I think a lot of people have. One day I overcame this and asked a woman who walked to the front of the line and got served first, “excuse me but can you please just let me know why you cut the line” and she told me she didn’t even realize and she apologized, the server apologized and I was served after that.
