I've occasionally gotten a quizzical look when I've shown my Rescue card from WASE/NASI, but I've never been turned down because of it. There was one time the look was particularly quizzical, so to avoid a hassle I pulled out my PADI AOW card, and the look went away.
I'm familiar with WASI / NASE ( http://naseworldwide.org/ ), but not WASE / NASI. Presumably typo.He probably read NAZI instead of NASI and that woulda made me look "quizzical" too
