Worst experience ever

In this past week my husband and a supplies when to wimpy for a casual work meeting, as they got to the entrance the cashier (Puleng) send them upstairs to go and have a seat she would send someone up. There was 3 other waiter that was standing next to her as they went up. They waited 20 min for the waiter and no one showed up, when the manager came to check if they are fine they said that they have been waiting for a waiter and no one has came up to even give them a menue. The manager asked who showed the customers upstairs and no one rep****. Afterwards my husband showed me who the woman was as i asked her why didn't she attend or send another waiter up as she said she would she said that i have a bad attitude and i wasn't there, so i asked the manager what happend on the camera footage and she told me, again today i said im going to report her bad service she came to me and said i must believe what my husband told me and also not what the manager told me because my husband is lying and the manager has something against her. So does the camera footage also ly and why would a MANAGER ly to a CLIENT? The manager came to me and asked what happend to day so i told her that i told puleng I'm going to report her and also not going to give her any service from my side so that she can experience what it feels like not getting any service, so i asked her why she wanted to know what i told puleng she said that they are calling her a rassist now, rase has absolutely nothing to do with bad services. We keep on going back to wimpy because we hope that their would be a change in service. N
