Damn Gi Chokes

I typically train with no gi here: http://sbgofal.com/

Once, while visiting my mother, I visited this gym: http://www.northmobiletkd.com/
They train in the gi. So I borrowed one and during the free rolling portion of class - this happened to me...

(skip to 3:35)

I tapped before I passed out. I just knew I was passing guard. But that's ok though...

Recently, while training here: http://www.westsidemma.com/

I bought a gi. Gi chokers beware!
