Missed Queue

Today was really weird...I got cut queued twice in a row.

I went to the downstairs canteen to tabao lunch & as I queued, the hawker actually missed me & asked the person after me what he wanted! Can't she even ask if I've ordered?

Then after buying lunch, I wanted to buy fruit juice. And the same thing happened! However, at least this one asked me after asking the one behind me asked me if I've ordered.
Am I invisible?
