In all of the years on this platform, I can't remember harassing a buyer, as most of my gig promotions are 30+ days. So that doesn't apply to a few sellers due to the type of promotion they offer. I have tried to cancel a few orders in the past for the reason you mentioned above. Mainly due to the nature of buyer attitude. The level of service each seller offers is subjective, but if you do each job to the best of your ability and try to over-deliver then, that should be enough.
