I nag my five daughters about being careful what they post on Facebook, probably the same way my parents nagged me to stop being such an asshole.

A message on Facebook’s “Spotted Cardiff” page alleged a worker sabotaged a customer’s meal in revenge for rudeness, Walesonline reports.

Spotted Cardiff is a page for Facebook users who “need to get something off (their) chest?”

The anonymous post appears to target a group of females who had threatened a female staff member at the Cardiff Excelsior Road drive-through in the UK because she “needed to smile more”.

The post said: “After over hearing the way you spoke to my girl on the head set be picking pubes out your teeth for a week.”

A spokeswoman for KFC told Walesonline: “We have investigated this incident and although there was an altercation in the drive-through between the customers and a member of our team, we do not believe the food was contaminated in any way.

“We have the highest standards of food hygiene and do not tolerate even the suggestion of this kind of behavior, and therefore the employee was suspended as soon as the matter came to our attention.”
