@KhanSaba1278 I know this post is fake just to get clicks, but in case it's not, yeah you're totally overreacting. Pay attention to your own life and stop trying to police what other people are doing with their own body in their own space.
@Avabelly__ That's less than 10%, which is not great. If the service was terrible then your tip was perfect because it was also terrible. 15% for restaurants is minimal. 20% is normal for good service. $120 is a bit much for her to expect, but $75 to $100 on $500 is reasonable.
