I'm the AFC from the other day

I take a friend along with me to the same bar. I realize this may be a fault of mine, but I'm going to explore more. My friend is pretty much Neil Patrick Harris, so he's an excellent wing.

However, as it turned out, I didn't need him. I asked out a hb8 on a date that I built rapport with previously, and she accepted. After, I saw a hb8 that looked like Khaleesi from Game of Thrones (long blonde hair, green eyes) As soon as I saw her, I approached her (I forget routines, so I just wing it), had a LOT of IOI and kino from her. The convo ended due to her bitch shield friend cutting in. I tried to be friendly to her and include her in the conversation, but she pretty much snubbed me and said "I'm just here in case guys say stupid shit to Khaleesi". I've never encountered someone who was so blatant about being the bitch shield. I ended the convo, but after a while Khaleesi was sitting with bitch shield making eye contact with me before I left like she wanted to talk more. Any tips on dealing with bitch shields would be appreciated.

tl;dr: closed two hb8s. Need advice on bitch shields.
