Restaurant workers of San Francisco, California, want to implement a standard tip of 25% onto the bill.

According to Contra Costa Times , the restaurant workers proposals for standard 25% tipping in San Francisco already have support from some high-class restaurants.

The main issue with their proposal is that diners should pay the 25% tip whether the service is good or bad.

Regularly, people are tipping on average somewhere between 15 and 20%.

Restaurant workers of San Francisco want to implement a standard tip of 25 per cent onto the bill

The San Francisco restaurant workers proposal comes after a recent incident, when a diner declined to tip a waitress in Washington and allegedly insulted her on the receipt.

Victoria Liss was so incensed by the diner’s comment and his lack of gratuity, that she has made it her mission to find the “jerk” responsible.

The waitress posted a picture of the offending receipt on her Facebook page and named the customer as Andrew Meyer, after she found the name of the credit card user.

The picture of the offending receipt was re-posted on Facebook, blogged, tweeted and reported on by several media outlets.

The proposal of standard tipping in San Francisco, however, has not gone down well with those living nearby.

Speaking to Contra Costa Times, Mike Alexander, from Antioch, said:

“They have to be kidding.

“The whole purpose of a tip is to reward service. If the price is dictated it’s not a tip.

“If they’re serious they’ll meet a lot of resistance. It seems like everyone is trying to squeeze another buck out of us.”

Another potential diner, Martha Haider, from Brentwood, also told Contra Costa Times: “I don’t mind tipping for good service, but 25% is going too far.”

“There might be some well-heeled people who will do it, but not me.”

Around the world there are wide variations for a standard tip, often leaving even the most experienced of travelers confused.

The tipping rules sometime can be extremely complicated and vary not only by country but also by scenario.

According to travel magazine Conde Nast Traveler, tipping in the Middle East is “complex and subtle”. While you may pay out often, it is usually in smaller amounts.

In some of the world’s poorer countries – including those in Africa – travelers are advised to not just be generous but also thoughtful.

Travelers are advised to always tip in India as it has been known for restaurant workers to run after people and scream for money.

In Europe, one rule is too always tip in cash and not on credit card. That way, the waiter or waitress will receive the money.

In the U.S you would be expected to leave between 15 and 20% on a meal. But in Latin America it is more like 8 to 12%.
