Depends on the severity of what you did for the comment to happen in the first place. I don't let them hold much weight... people tend to be more bitchy and negative in comments because here used to getting what they want.
As long as you didn't do anything really terrible and can explain your story to a manager/supervisor (if it comes to that) you'll be fine. Don't sweat the small stuff.
If you are sure that the customer will complain, you could go to your assistant director or store manager (if you have decent relationship with them, and you know you did your best with the customer) and preemptively tell them about your experience with the customer. If you did something wrong, apologize and if you learned a lesson from it, tell them so.
If the complaint wasn't made yet, there is a good chance that it will not happen. Keep your fingers crossed.
I don't think you would get fired from it. You may get written up if this is a pattern and you have been already warned. But everybody knows, that customers can be a PITA. So hopefully they just tell you not to do it again and to get a manager when situation with customer escalates.
Again it all depends on what happened, but more times customers do not want to hear anything you say....only their story. I love how you will have 100 Customers that love you....etc And then 1 customer complains because your SO HORRIBLE....and they want to write you up...etc
True. Never had a customer go to manager to give a compliment about an employee. Customers seem to mostly complain. And that's maddening.
You can bend over backwards, be super nice to them all, and hear direct compliments to you from many of them. But the one who will be unhappy about something will be the only one who will make a written comment. Because statistically, angry, unhappy people are more likely to write a comment. And that will make you the bad guy, because compliments 0, complaints 1. It's like "written comment, or it didn't happen". And that's not right.
