Well, I don't think anyone is perfect. Looking back, I could not believe I ever made the mistakes I did a while back when I was a newbie. Yet, the shops all went through. I would not be so sanctimonious to think I am incapable of making any error again. It would just be easier to correct any boo-boo, if it could be corrected. It is from learning from our mistakes that we become better shoppers. For instance, no amount of bonus could persuade me to ever overbook again. I know when I could easily make short cuts and cost me the shop.
And based on the fact that the schedulers were willing to wave their magic wands indicated that the OP was a trusted shopper to them. It is in those little things that the schedulers do to bend over backwards that show the shopper is a keeper in their eyes. Perhaps she has done a number of things to save their butts, too, like taking a flaked shop or a disliked shop to get it off their list...even without a bonus. Even sacrificing a more important shop, moneywise or funwise.
Or perhaps doing something more to save the shop is in the schedulers' nature. But I bet they don't do it for every shopper. I give OP (numbernineteen) the credit for having that 'something' to encourage the scheduler or the MSC to be on her side and remember that without one or the other, there is no successful shop.
