Whatever happened to my seat and a 'standing ovation'

Arrived at the Millennium Centre in good time to pick up my tickets for the show "The Producers" by Mel Brooks starring Peter Kay, I was so excited, it was a treat for my daughter and I had ordered the tickets on line. I was so proud of myself until...

"Sorry we haven't got any tickets for you" the receptionist said checking her records "We are in seats K36 and K37" I offered helpfully. "No, I am sorry someone else has those seats...oh, you should have been in the matinee performance this afternoon"
"The matinee performance" I put my hands up to my head and my elbows on the desk...I couldn't say anything else. I had pressed the wrong button on the computer and booked the afternoons performance by mistake!
The young lady seeing my distress got straight on to the manager who within minutes realising it was a genuine mistake offered us two seats. The performance was a sell out we were so lucky to have obtained those seats.
The show was wonderful, a feast for the eyes, funny, extraodinary, when it ended my daughter and I got up on our feet to give them a standing ovation. My daughter looked around and saw that we were the only two standing so sat back down again....but I stood, good grief the performances I had just witnessed were well deserved of this little action of apprecation.
With that Peter Kay stood forward and said "Ladies and Gentlemen, please take your time sitting back down in your seats, you miserable bast..ds" Good for him I thought then he proceeded to list the awards the show had won Cory English he played Max Bialystock had run away with a very big title award but I can't remember what it was and the musical itself had been voted the best on the circuit and yet the audience who had howled with laughter all the way through couldn't find the energy to get out of their seats and give a standing ovation, such a little thing to ask, and it gives so much encouragement and pleasure to the cast.
