Starting Sunday, bar and restaurant managers could face major lawsuits if they so much as allow a customer to call a waitress "love," The Daily Mail reported Monday.
Bar managers reportedly have been advised to display signs warning that, "harassment is not tolerated."
The new rules were driven by Women and Equalities Minister Harriet Harman, who maintains authority with European law to change regulations relating to discrimination.
Some politicians and lawmakers reportedly feel the new law is going too far.
"People will start to be afraid if they call someone young lady or my love. It is impossible for an employer to control customers in this way," said Jill Kirby of the Center for Policy Studies.
