Freezing cold venue

The setting is absolutely amazing, ....... I recently attended a companies dinner dance which started off superbly.
This didn't last long, as we were guided to the banquet area in the marquee, we were hit by temperatures of, I guess somewhere around15 degrees centigrade.
It was beyond belief, and the temperature never changed all night.
Our starter arrived 15 minutes after everyone else's on the table, but was a nice hot bowl of soup.
The main meal was ok but the accompanying vegetables also very cold.
Hardly any gravy, when I asked for more actually received it some ten minutes later after I had finished.
The worst was yet to come.
This was having to be out of the room by 9am and as breakfast was some 25metres away across the car park just added to the frustration.
No choice of breakfast offered, full English or full English.
Make sure you read the small print, I didn't.
All in all a poor evening.
