Complaints

So after classes today with my friends we decided to go and take a bite at Debonairs Pizza, so we even had a drink,we asked for glasses and they gave us ...after sometime we finished eating... unfortunately one of us accidentally dropped the glass,and we apologized but one of the cashier told us to pay R50 for the glass, we refused and asked why would we pay R50 because it a restaurant and we didn't do it deliberately...and we asked for a policy where it written that when a costumer breaks something should pay...rather they decided to tell us to clean the glass we didn't mind to,they gave us a broom then one of thier staff was steering at us and my friend asked why are we even cleaning because it not our work is to do...rather than him answering us ...he insulted us...he actually verbally insults us.....this happened at Durban Mnyandu Mall
