said by INtheKnow :Maybe not for the first or second offense, but it's definitely going to be acknowledged and dealt with. There are other factors that you are not considering that make such participation problematic for all.
No one is going to get fired for helping a customer. That is crazy what buisness would run that way.
The only way anyone is going to get diciplinary action taken aginst them would be by participating in conversations that bash the company or ones that are disrespectful of the customer.
And i can say that 100% of the cases that i'm aware of the person was fired for bashing customers not the company.
