Be wary of potential ticketing pitfalls
is always controversial. It's just not possible to keep everybody happy.
There's never going to be a stadium large enough to accommodate all the people who want to watch the men's 100 metres final and, with so much money needing to be raised from ticket sales, those lucky enough to be given the chance to attend will often complain that they're being charged too much.
So when London 2012 chairman Lord Coe and his team sat down to begin work on their ticketing strategy they were well aware that they would be criticised whatever they decided. They also knew that they could do absolutely nothing about one of the most common complaints.
