Me too agree with skvnair, same happened to me in Saravana Bhavan. i have reported to the floor supervisor, he admitted that the order slip is misplased. this was happened couple of month before also some restaurant we have to wait hours together to get the table during weekends. Now i understand this is usual problem in most of the restaurant. about attitude we have to inform the management, however no management will tell to neglect the costomer, eventhen if management is not rectified they are the one looser.
