I'm thrilled that my schedule is nearly always fully booked lately, but i am having some problems with some clients because of this. They are used to calling in 1-2 days before to make an appointment and now it is often impossible to fit them in at the time/day that they want to come in. No matter how much i insist that they have to book ahead of time, they just don't listen to me! So now i have clients becoming upset and threatening that since i can't fit them in they'll have to take their nails off. How annoying is that? Like they're threating me or something. Is this a common problem? And does anyone have any solutions. I always do my best to fit them in, even sometimes offering to work after hours (i have cut back on this alot though.
