To be fair, my initial reaction was that if people wanted to vote so badly they should not have waited for Coronation Street to finish before they went to do so.
Then I reflected on how long it had taken me to cast my vote. Went to my polling station at 6:30 (incidentally, not the one at the end of my street, the one a mile away!) only to find a long queue. When I finally got in, after about 40 minutes it was clear there were two tables to collect your ballot papers, each table responsible for certain streets within the area. The table I'd queued for had a huge long line and the other table had no queue at all. So basically, if you lived on one street you had to wait an eternity and if you lived on the next street along, you could be in and out within two minutes.
When I finally got to the table to collect my ballot papers, I indicated that I had my vote to cast and a proxy vote on behalf of my flat-mate. I was told I'd only be allowed one vote at a time and I'd have to re-join the queue to cast the proxy vote. By this time the queue was almost twice as long as it was when I first joined it (and obviously the queue for the other table didn't even exist!).
It really was a bit of a shambles and to top it off, the polling station at the end of my street which I wasn't allowed to use, was very quiet all day.
On the basis of my experience, I can well imagine that people could have arrived well before 10pm and still been denied a vote. No doubt it will all be swept under the carpet but the system really does need reviewing.
