You can imagine this situation being parodied on comedy sketch show.
Nice middle class lady, used to ordering tickets for concert halls and opera houses decides on a whim - or rather inspired by an email - to book tickets for a rock concert. (Imagine Lady Bracknell saying 'A Handbag'). Actually, not a rock concert as such, but pretty damn close. kd lang in November! Ooh, ooh, ooh!
I go through the various transactions pages, and discover that, in addition to the face value of the tickets, I am also being charged a £7 service charge and £2.50 processing fee.
Remember nice Lady Bracknell.
"But the Royal Opera would never do this!"
But, despite my chagrin at what I regard as a rip-off, I have booked two tickets. I don't know if Himself will want to go. If not, I'm sure I shall find someone else!
