I really do feel your pain Samantha, but I personally think curly hair often does demand more work and time if it's skillfully cut and styled.
I have really thick and long, curly hair and understand that my hair is so much harder to manage than someone with thin, short, straight hair. If I saw me walking into some salon I worked in and wasn't used to really curly hair, I might just break into hives and faint. So I get that it could be overwhelming for those who aren't used to it.
The extra expenditure is worth it IMO, provided the person truly is good with curls.
