If you play APA league it is un- sportsman like but certainly not a loss of a game. I see people break down their break cues all the time as if it were no big deal. If you consider breaking down a cue to protect it rather than leaning it on a bar table or cue holder during the match I think YOU should be disqualified, how ridiculous to take the game that seriously.....I've had a few occasions where I forgot to assemble my shooting cue before the match begins, should I be disqualified? Chill out guys, it's pool, and half of you are never going to be in any position to make such a call anyways...so take your cake and eat it too, just don't make us try your recipe. Read the rules on the official sites, use your best judgement and make the best of your own judgement, but don't call such a critical foul when you really don't even know wtf your talking about.
by the way.....poolplayers.com is the official APA website, or bca-pool if in bca league. I really don't know your circumstances and if you were DQ'd for that in APA you need to address that with your team captain, cuz that is complete BS. So if I were to put on a different shaft so that I could apply my bridge to it that is a foul? Than I guess everyone I've ever seen on APA should be DQ'd. That's a bunk call. Maybe BCA is different but I see this kind of thing all time in APA.
And while i'm going off here, assuming you are in APA, watch what they call cuz a lot of the time they get it wrong, I would get a APA pocket book if I were you and take it with me every time I play. I've been called on a bad foul before, and regretted not having definitive proof to show otherwise. Be careful and keep it legal, some rednecks just don't know wtf they are talking about.
