So my makeup/skin care lady and I have been trading services for a about a year. She gives me monthly facials and I babysit her little boy in return for enough hours to cover the cost. She is doing my makeup and all my BMs makeup for the wedding (6 of us total) and in return I'm babysitting for her enough hours to cover the cost of all of that, plus travel to the location. I'm also going to pay for all her meals that day and I was thinking of getting her a nice thank you gift for everything she's done for me. She's such a great person. Would it also be a good thing to tip her as well? Or because of our trading would the babysitting, gift and meals be sufficient? I definitely want to show my appreciation and gratitude for her in the most appropriate way! Thanks for your advice!
