Extremely Bad Service

I would like to think that interupting people while they are eating Is just a sign of basic manners and if one did not learn these at home, it should atlease be part of the customer service protocol for any company, today we went to have pizza at debonairs after along day of shopping, while we were sitting having our meal a rude sataff member came and told us that we had to move because she had to sweep the floor and mop, we then had to move our all our bags and our food to the next table, after we were done eating we decided to go and talk to the lady and tell that she should not do that again as it was bad menners, she was very checky and told us that she was right in doing so as the shop was about to close, she then offerd for us to speak to her manageer. Who also came in her defence saying that the waitress was right in moving us and if we ddnt want to move it was our right to say so, the manager was so rude that she even left us unattended while we were still talking to her, she made it clear that her staff was right, as they were about to close we needed to be out dof the shop, now is this the kind of service that we should expect when walking into a debonaars?
