Can be summed up in this picture. Why would he buy Bree? We don't know a Bree and if we did I doubt that I would like her. I would never pick a name of someone I didn't know or someone I didn't like. I would pick a generic BFF, family, friend, or something endearing but certainly not just pick a random name.
After seeing this I have to wonder, did he look for another name? Did he pick the first one he found? Maybe Bree is some unknown past love? Does he even know that it has a name? Even if I really wanted a coke I wouldn't have walked out with Bree, I would have settled for Dasani.
