I was at a club last night and having a great time. I was coming from the bathroom and I noticed these 2 guys having some words. So being the fight loving, adventurous guy that I am I stayed there to hear them out. One guy was [censored] because the other guy asked him to please move so he could walk by him. Yeah I know, dumb. Well the words went like this. Guy "A" (aggressor) said to the other guy "If you have a something to say to me, than say it". Guy "B" said "I just ask you to move but if you want to start something (steps up into the other guys face) than I have plenty to say to you". They stood there face to face and finally the Guy "A" just walks off. About 5 minutes later Guy "A" blind sides Guy "B" and got a few hits in before the Bouncers pulled them apart. Guy "B" clearly had no chance at all because of the so called "sucker punch".

I don't think Guy "B" was wrong in standing up for himself because I am a believer of "honor" and plus he wasn't rude to ask the guy to move please also.

Guy "A" clearly a coward wanting to look tough in a crowd but only made himself look like a coward by "sucker punching" to get an advantage for a stupid fight reason.

What are some of the things you do at a club to avoid these situations if they arise?

Tell guy "B" to watch out, and hope you do not end up in a similar situation. People can be stupid and irrational

Pretty much echo what Cord said. This is a trivial thing to get in a ruck over. What a lot of people forget in these situations is that if you escalate it you never know how big or serious its going to get. Would you really want to do time in jail just because you wanted to walk past someone and they acted stupid.
The only other thing I would do after what Cord suggested would be to keep the guy in my peripheral vision for a while and pre-warn the club security.

I'm not exactly a pacifist,but I know when to avoid trouble. Being in a club where there are lots of diverse people is a good place to practice avoiding trouble as there most likely trouble to be found.
What you had here were two macho guys trying to save face. Big deal,someone asks me to move,I say "no problem," then I move someone asks me if I have a problem,I say ,"no buddy,I'm just here to have a good time,would you like a drink?" I don't care how big or small they are or if I think I can whoop them,but I do have different moods. It's best to stay away from the drinking masses anyway.
