10% Tip as Default

Add this feature that already sets 10% or whatever percentages the company uses as a Default, so the customer doesn't need to click on "custom tip" to add this!

A customer called telling them that were not able to add tips because the amount was not changing! She did not click on "Custom Tip", so she had a hard time and did not add it! (She is a old lady)
