I wish I had a new wax tech
Is there something wrong with your current waxing tech?
She's so slow. I don't have time to wait for her to be finished.
Wanting to get your waxing done in a timely manner is completely understandable. You're paying for a service and it's your money so of course you should be able to chose who you want for your waxing. I hope a person suitable for you is available.
I really think that you should need to be licensed to do this and someone isn't reliable or skilled we should get a different one.
Yeah, it would be really risky to have someone wax you that isn't certified! Always be sure to check one's credentials so you can get the best service.
