He wouldnt necessarly be covered in blood. I also got jumped by around 10 locals a few years back during a birthday night while everyone was drunk after my ex at that time was shouting at me and told his friends to beat me up. I got a table thrown on my back (not a big one though, thanks god), some beers bottles, kicks, and alot of random thai shouting and i had nothing really beside a very sore body the next day. As long as youre aware of whats going on and have a good view (in my case i was looking in between my fingers while covering my face) and know whats being thrown at you, you can adjust your body in a position to minimize impact/damage (obviously, easier said than done).
I guess my point is getting jumped doesnt results in ending up in a pool of blood necessarly.
