'So you are not happy with your Harvestmath pony? Well, I can offer you an exchange, as I would not want one of my ponies where it was not desired. However, this is not a decision to be taken lightly, so I will give you a moment to think about it.

'If you are certain you wish to exchange your pony, speak to me again, and I will give you a receipt in return. You can then exchange the receipt for a different pony.'
