I don't get bored with selling.. I go do email, play another game, or even do something useful. I'd surely get bored after a while if I just sat and watched them window-shop. This is, after all, casual gaming, not meant for constant monitoring. Though I do appreciate Fish Tycoon's cash-register "ka-ching", the only consequence of not knowing when the plants are all sold, is that the "number of visitors" stat increases. If there's an issue with not wanting to leave the greenhouse plants unattended, I just put it on "pause" before I go to the nursery--the selling continues normally. Sometimes it's easier to change what I do than what a game does, and makes me just as happy.
