Cut queue auntie

Wah, just now while I was waiting for cab, this auntie popped up of nowhere. Think she wanted to cut queue and tried to talk to me, to give the pretense like I knew her (混水摸鱼）. She even asked me where I'm taking the cab to (which of course I didn't tell her).

I simply told her (hopefully loud enough) that the queue is over there (pointing). When I said this, she said in mandarin "oh, I've queued for quite long already"....
Well, I had been queuing for like half an hour and I didn't see her at all in front of me. Come on, I noticed who was in front of me. I was too tired and aghast to respond, so I ignored her, giving her a "look".

Now I regretted, should have told her that she was not there the whole time I was queuing and maybe the people behind will know what she was trying to do. She didn't dare take the cab before I did, saying "你们走了我才走", i.e. she'll wait for us (as in the people in front of me, including me) to go off 1st".

Think she tried to "insinuate" with me coz I looked like a local or at least of the same race. The 2 parties in front of me were Japanese & don't know which...Malay, Filipino?
