Unacceptable behavior from Supervisor

My friend received the worst treatment from a supervisor named Anna cause of an injury to her knee which does not enable her to bend her leg . The supervisor caused such a scene cause her foot was on the bench 😳 without enquiring she instructed her to put he foot down how inconsiderate from a whole supervisor. Imagine having to leave an establishment cause of bad customer service not from staff but a supervisor 🙄 Nandos Middleburg please retrain Anna on customer service
