I am hiring separate hair and makeup artists to come to our hotel on the morning of the wedding for the bridal party. The hair stylist charges $80/bridesmaid and $100 for me. The makeup artist charges $120/bridesmaid and $180 for me. I will be paying mileage charges and parking fees for both. Each vendor is self employed (not working as part of a salon/agency). I've received conflicting advice concerning gratuities. Opinions have ranged from "no gratuity is required as they are in business for themselves and receiving the full amount charged" to "20% of the total service."
(I generally tip 20% in a salon setting.)
Obviously I don't want to be stingy, but I also don't know if $300 in gratuities would be excessive? What would you recommend?
