Should Have Paid More Attention In Regular School

(I work at a motorcycle training school. A boy rings for training for him and his dad. We have motorcycle training for learners which is done every two years; this is cheaper on renewal than the first time you do it. The boy is asking for two slots, one for him and one for his dad.)

Me: “Okay, as a deal, we’ll do that for £200 for the both of you.”

(It turns out his is a renewal and it’s a first-time course for his dad.)

Me: “Oh, in that case, it’s £80 for you and £110 for your dad.”

Caller: “But you said £200 for both!”

Me: “Well, okay, then. As I promised, we’ll do it for £200 between you.”

Caller: “Great, thanks! See you next weekend!”
