during my training (still going on atm) i had someone ask me 3 times if they could come up, so after great expence, i managed to talk my instructor to all someone to come up for a lesson. (a lesson where its safe or easy to have someone in the back), and even arranged a good time, all they had to pay was a £10 insurence thing, which they said no problem to. the day came, and they said, na i cant afford the £10 this time, and dont really want to pay £10 to go.
(i was thinking i told you weeks ago you would have to pay this, and you still wanted to come)
i mean i was paying £140 for the lesson, which i made at a time more to suit them, and had arranged a lesson that would allow them up in the back.
needless to say, even when they asked again i just said no.
