What is the meaning of 'a single' in this context?
Richie: It's an "escapulario".
Agustine: Uh, no. I've never even seen something like that before.
Agustine: (Chuckles) Well, I don't know a single Cuban who'd wear something like that.
What does "a single" mean in this context?
That means unmarried person never wear escapulario or
Agustine has never seen Cuban who'd wear escapulario before?
I'm not sure which meaning is correct.
If you could answer me with this, I'd really appreciate your help :)
