I have one of my ladies coming to get Shellac done tonight, I haven't seen her for a month or two but she normally comes to me for her treatments. Her daughter got Shellac done at the beginning of the week and she was with her. She said she got a voucher so had her shellac done else where - they made a lovely job. Anyway.....she is coming to get her Shellac done with me tonight but she will be expecting me to remove the other nail techs Shellac - should I charge her for this. Normally I incorporate the cost of removal of Shellac within the price I charge to encourage them to come back for removal, but of coursec this is not my Shellac. Not sure what 'the right thing to do' would be. Any advise would be gratefully received.
