This is unfair and there should be a time limit of being kicked from the game if not playing. On the subject of the Grand Prix i dislike when big money players come in and bet trillions to get to the top of the list and then just wait for the countdown without playing again and finish first place. Maybe there should be some way to disable notifications while playing. I hate when you are in a Goldies Grand Prix race with seconds remaining and a minor achievement pops up using valuable seconds and even costing you first place.

Apart from the obvious of coins being way overpriced there are a few in game things that i dislike.
