hello, i saw a girl wanting people to try a sample of a juice. I waved at her and she waved back, while i grabbed some magos before going up to her. I asked her where the juice was and she told me line 6 and she asked if i wanted to test and i drank some.

I wanted to bring up a topic but the girl based on her tone, appeared like someone that did not want to be there. I did not even asked about the flavors of the juice or anything, her mood was just kinda dead. She was outside the supermarket too sampling.

I hear not to approach when someone is working but how do you handle someone that's moody or idk how to explain. do you try to make them laugh to change their mood or do you withdraw like how i did?
