CMV: Takeaway food outlets should accept orders up until their advertised closing time.

My wife and I visited a restaurant late last night (a Wednesday night) whose website said was open until 10pm; when we got to the place at 9.35pm and found they were "open", we were advised that we could not buy any food - the kitchen equipment had already been turned off and they had begun cleaning since they closed at 10pm.

We checked the signage on the door - it listed their opening hours as being until 10pm on this particular night of the week. There was no sign at the entrance that stated the kitchen would not be open until then. There were no signs anywhere visible inside the restaurant that the kitchen would not be taking orders up until 10pm. I explained this to the server and his response was essentially a shrug and a recommendation of a place down the road.

In this country, there is a piece of legislation called the Fair Trading Act, which protects consumers from things like fraud or false advertising; it is my belief that stating you are open till 10pm but refusing to serve food at 9.35pm certainly qualifies as false advertising.

Change my mind, people - why am I wrong?
