I made the point that this policy was discriminating against single theatregoers. In response, the rude woman told me I should find someone to go with me, in a way which implied I was 'sad' for wanting to go on my own. She then made the point that it was the same as a group of 3 wanting to book for a show, but there being 2 seats left. That's clearly not the same: there there are not enough seats left, where in my instance, there are. They just wouldn't sell one to me.
Anyway, rant over. I booked in the end, as someone in my family said they'd quite like to see it too. But I was not impressed with Delfont's customer service.
I get why they don't like to leave single seats (in spite of the apparently overwhelming evidence that there are lots of single theatre goers) but surely they can't refuse to sell you a seat, how isn't that discrimination? As for telling you to find someone else to go with you. I guess they sell the seats so don't care but that's shoody behaviour.
