I've had waxing for more than 8 years, and I've never felt so awkward; no conversation, not eye contact...nothing.
Also, I left with a couple of burns on my arms.
When the waxing was done, the girl asked me if I already paid; I told her I did through Treatwell. She left me in the room so I could get changed and, when I finished and I left the room, no one was there to say a simple "goodbye".
I won't recommend it.
