People said, "When tipping in Pokemon X and Y, it increases your chance of getting a shiny", Is it true?

Question

When some people in Pokemon x and y, said if you want to tip, does it increased your shiny percent?
For example:

before tipping : 10% getting a shiny
After tipping : 15% getting a shiny
(Is it true? Am just asking! This is not a real example but will it happen like my example did?)

Answer 1

Increasing shiny encounter chance is a only a rumor, but it does increase your style points.
