It was definitely yuyu, confirmed through wechat picture. Maybe she swallowed too many loads that day? The place is BUSY. Wendy wasn't working at the time, I had the first stall since there was a guy in hers. And like I said, multiple calls and buzzers during a 30 minute session.
While I was there at least 1 person left, 1 person came in, 1 person was turned away. 3 calls in english making appointments, 1 call in mandarin making appointment, and 1 in rapid fire cantonese which I didn't catch.
This place is more busy than house of joy, but with no dedicated receptionist and only 1 person working. Bonkers.
