Guy raps/sings in grocery store, maybe produce section?

My wife in convinced I either made this up or dreamt it. Please help me figure it out!

The scene i can remember is:

a woman meets a man (possibly younger than her) and he tells her hes got a music gig coming up and he then invites her to see him perform. When she arrives at the address, its a gorcery store. She thinks its a mistake but goes inside and there he is in the produce section? On a platform rapping about vegetables to customers. She thinks about leaving but he sees her...

That is the only scene i remember from the movie. It is a somewhat recent american movie, in english, both the woman and the man are white...
