Sent my thicc gf to pick up alcohol from a stranger, I can show her

I sent the guy a pic of her and he got so excited he wanted me to send her alone ahaha. I didnt mind, but she doesnt want to meet strangers at all. I had to tell her I know him, and I even gave her money to buy the alcohol with. Eventhough I knew the guy said he wanted to negotiate the payment with her once she goes to pick it up
