Notice of service times mean nothing

At 20:45 on the 25th December 2020 O took my family to Macdonald in Herm**** only to find the store closed even though the notice displayed indicated the operating times was from 09:00 to 21:00 When we questioned the on duty manager Trabant we were then rather rudly told that 21:00 is the time they leave not when they close the store to customers and should they serve us they would be fined I find the attitude of the staff very ******** and blatantly rude The fact that the info displayed on store windows states one thing and the staff say another can be seen as false advertising and this matter will be taken to the consumer protection I have taken a picture of the in store notice I have a feeling the CEO of Macdonald South Africa won't ever hear of this until the CPC informs him and as a ***rd won't bother to contact me but rather hide
