At the bathroom of the hotpot place in Richmond, BC they had mouthwash and cups. Also they had ear cotton buds which I don't understand either. Mouthwash makes more sense to rinse your mouth after food but if anyone uses it directly from the bottle then there is more risk of catching a cold. I would never use an opened mouthwash that anyone can tamper with other than my family's one. Could easily poison someone etc and not be easily caught as bathrooms don't have CCTV.
What do you think?
