Coffee shop AUs are my happy place. Hoping someone can help me find this one!

This one I'm pretty sure had Gabriel as the barista, and Sam would come in for coffee. I remember a scene where Sam came in and was surprised that his coffee wasn't brought to his table, and then realized that Gabriel was the only barista who did that (and the other baristas were annoyed with Sam's obliviousness). It was similar to Whit Merule's "In which Gabriel is the king of flirting," but it's a different fic.

Thanks!
