How much do you tip?

Here's a tip for service industry providers, millennials will pay more for your product, but not for the tipping.

A new study found the generation from ages 18 to 37 doesn't like to tip, with one in three leaving less than 15 percent at restaurants.

The online survey, conducted by creditcards.com, revealed millennials will pay more for what you offer, but when it comes to gratuities they play their cash close to the vest.

They also chose the lowest preselected tip options.
