Was she flirty or friendly?

I’ve been going to a cosmetology/barber school to get my haircut for a couple of months and yesterday I had a new barber, we’ve never seen each other before. Throughout the 2 hour haircut these are some of the things she did that have me conflicted:

•She talked to me a lot and kept the conversation going the entire haircut. • We teased each other repeatedly throughout the appointment. • She playfully hit my arm or tapped me whenever I teased her back. • She grabbed my wrist to cover my watch when I checked the time joking that she was taking too long • She placed the clippers directly on my ear as a joke to make it louder after I mentioned why I couldn’t hear her • She stood very close to me while cutting, close enough that her leg or thigh touched my arm or shoulder multiple times. (Might be over analyzing) • She spun my chair toward her friend and said “here, join the conversation.” • She told her coworker I’m funny • She teased me about smiling too much. • She asked why I was side-eyeing her while she worked. • She told me to stop looking at her, bc I was making her laugh. • She asked how old I was. • She joked that I was “an old man.” I’m 21 she’s 18 • She asked questions about my school and what I do in class. • She opened up about her family, very personal things • She pointed out her insecurities • She joked about how she is outgoing • She made jokes about my baby face • She said she is the only one who should cut my hair. • She told me which days she attends school so I can book with her specifically. • She talked about her sister dating a guy and when I asked what he does for work she joked “idk that’s not my man.” • She followed me to the front desk after the haircut.

Is it possible that she’s just trying to build good rapport with clients or should I ask her out at the end of my next haircut with her?
