Cultural insensitivity _ catering requirements

Matric dance held on 15 Oct. Catering requirements indicated upfront however not provided for. It's a holy month of vegetarian fasting 17 Sept to 17 Oct (Purtasi) . There was no vegetarian starter and when staff were asked they said they didn't have anything. For mains people were told there was only a buffet and they could eat the side dishes provided. Part of the cost of the entrance/ticket would have been for food which was poorly and insensitive not catered for. Poor showing. I wouldn't recommend.
