I work at retail in a mall, and there is a kiosk in front of our store with multiple staff.

we used to say hey randomly once in a while but few days ago one of the girls who work there cam in the store while i was at cash, we introduced each other and greeted and she bought something.

since then whenever she see me first time in the day she wave hand and smile asks if im good.

I found her ig but prefer to no approach this way, she is usually standing close to her coworkers but i can ask her to move a lil further.

so I need help how to approach, tnx
