Not tipping your server and other rude money habits

Money can be a touchy subject, so how you approach it with others may take some extra thought and consideration. And although everyone has different levels of comfort when it comes to how they approach finances with friends, family and people they are doing business with, some behaviors are outright rude no matter who you are dealing with.

Asking How Much Someone Paid for Something That You Have No Intention To Buy

“It’s not polite to just ask prices of things,” said Jennifer Porter, an etiquette expert and manners teacher in Seattle. “Some people love sharing prices, but unless it is offered, that is private information.”

The exception to this rule is asking about pricing for something that you are interested in purchasing.

“It can be appropriate to open a conversation about how you’ve been looking for X and wondered what range a friend paid for a similar item,” Porter said.

Asking To Borrow Money From Friends

Porter said that asking a friend to lend you money is an etiquette no-no. You may borrow money from a family member under certain circumstances, but if you do, have “a written plan and timeline to pay it back and offer to pay a small interest rate or whatever the ‘lender’ stipulates,” Porter said.

Discussing Salary

It’s rude to ask how much money someone else makes, and it’s also rude to share how much money you make (unless there is good reason to do so, i.e. someone is looking for a job in your field and wants to know a typical salary range).

“This can make people feel uncomfortable,” Porter said.

Not Tipping at a Restaurant

Arden Clise, founder and president of Clise Etiquette, said that not tipping appropriately at restaurants is even ruder than usual in our current economic climate, with many restaurant employees out of work for long stretches of time over the past year.

“Tips today should be at least 18% of the bill,” she said.

If you were unhappy with the service, you may leave a lower tip, but you should not skip tipping altogether.

“Keep in mind the waiter isn’t always at fault,” Clise said. “It could be the kitchen was backed up or made a mistake that the waiter had no control over. If you were unhappy with the service, leave a smaller but still acceptable tip — no less than 15% of the bill — perhaps with a note about why the tip is small.”

Telling Someone They Spend Too Much Money on X

How people spend their money is not yours to judge, so you should keep comments to yourself if you think your friend spends too much money on shoes or your neighbor spends too much money on toys.

“It may be your neighbor has a lot of recreational items, but that’s not any of your business,” Clise said. “Everyone has different spending habits. Some people spend their money on toys, others on vacations, some folks are penny pinchers. There is no right or wrong.”

Not Paying for a Meal You Invited Someone To

If you offer to take a friend out to dinner or lunch, you should pick up the tab.

“Whoever invites the other is the one who pays the bill, unless you agree to split it in advance,” Clise said.

Ordering a More Expensive Meal When You Know You’ll Be Splitting the Bill

When you’ve already agreed to split the bill, you should keep your ordering in line with what your companions are ordering.

“Ordering the most expensive item on the menu and/or ordering an alcoholic beverage when your dining companion doesn’t drink and then asking to split the bill [is a rude money habit],” Clise said. “It is also very rude when you are invited to join friends for a restaurant meal and you know they will pay the bill, and you proceed to order the most expensive item or alcoholic beverages that they don’t share with you. If someone is paying the bill, order moderately priced dishes and forgo an alcoholic drink unless your friend is joining you.”

Not Contributing Fairly To a Potluck

If you’re invited to a potluck, bringing just enough to cover yourself or one cheap item is considered rude.

“It’s polite to bring something of value that others can enjoy,” Clise said. “A couple of beers won’t go far. Showing up with just a bag of chips is also rude when others are bringing full dishes.”

Not Offering To Pay for Gas When Someone Gives You a Ride

Especially on longer trips, it’s rude to not pay for gas if someone else is driving. For shorter trips, it can also be rude to not offer if it becomes a habit.

“Someone who asks for a ride all the time but never ever offers any money for gas [is rude],” said Maryanne Parker, an etiquette expert and owner of Manor of Manners.
