Sorry, but if the ad specifically says BBBJ and I get there and am told it'll have to be CBJ, I'm walking. I personally hate CBJ. If a lady is CBJ only, and she's up-front about that in her ad or in our pre-visit communications I will usually pass, unless she's offering something else that I really want. Even if I choose not to see her, I appreciate the up-front honesty about it.
Listing BBBJ in the ads, and then pulling a "CBJ only" after I have arrived, that's not cool, not cool at all. I am a polite guy, and I try my best to always treat the ladies I see with respect and kindness (unless they don't want me to...
.....), but I think I would have walked out in that situation. That is 100% "bait and switch".
