Thats a really good idea. Especially about the amount of money it costs you. We had a girl not turn up for nails, then called in afternoon to book eyebrows, when she came in she said she forgot, can i book for next week? and did the same blooming thing the next week. Had a full body massage not turn up also on saturday (but in hindsight i think that may have been someone playing funny b*ggers with us as it was a wrong number)
we get it more with beauty than with hair. I think its because when your roots need done, they need done, whereas a massage aint as "essential"
