There were two men ahead of me in line...the one right ahead of me was slight and much shorter that I am...I thought a forearm choke from behind would be nice for him....the other was bulky and slightly taller, though not as tall as I am. His pony tail would provide a good place to grab as a kokyu nage redirected his head.
Do you guys ever think like this in public?
It's a near constant process for me. I size up everyone everywhere I go nearly and plan out what I'd do if something were to happen.
