Inside the white cup..
Q:
There was a large amount of green stain on the inside of the white glass.
I took a sip without noticing and felt very sick.
I imagine you've received many complaints about the glass cleaning process, but do you have no intention of improving it?
A:
Regarding the washing of teacups, we previously received a similar complaint, and in response, we changed our operation to include bleaching twice a week in addition to regular washing. We have not received any similar complaints since then. We
will share this feedback with our staff again and re-examine our work operations and checks.
