Earlier quoted context omitted.
That might be the way to bet but casually mentioning a lawyer once worked for me on a used car warranty claim. I didn't make any threats, I just said "my mechanic says X and my lawyer says Y" and they said we'll call you back, which they did in ten minutes and said I was covered after all.
If that's actually what your lawyer says, then there's nothing wrong with that, but if you don't have a lawyer and they call your bluff, you're worse off than before you ran your mouth. So it's not really too much different than me telling about that one time I was in Vegas and I rolled a seven.
It was under a thousand bucks so I could have just taken them to small claims court if they didn't fold. That may have worked in my favor.
