That's the point I was trying, rather badly obviously, to make. I say thank you for the booking at the time it was made, because as you say, it's simple good manners, and I say thank you when people pay me, again, simple good manners, but you said "Thank you for asking me", which is different to thank you for letting me DJ at your venue
