Not sure if you read the section below that where I talked about the part of the pitch that I feel is responsible for these issues. I don't rule out that a Account Exec wouldn't say something like that, but from my experience, Yelp is very serious about such instances and will most likely fire somebody who does that immediately. I say most likely because even with their exceptional training, people do make mistakes and that person might be able to convince Yelp it was unintentional - then again, I wouldn't be surprised if Yelp is at the point where they would fire somebody even if it were accidental.
There very easily could be an exception, especially with the number of Account execs they have right now, but it's clear from the very start of training to making actual calls that such actions will not be tolerated.
