Mr. D. doesn't pay drivers properly, so don't order there !

I was regularly ordering food. Now I realised they have changed the settings, giving the driver a tip of 10 %. These drivers are employed by Mr. D. Mr. D has to provide a proper payment. It is aIsn't it enough that they raise the menu price by up to 20 % for their profit ? It is absolutely not acceptable that they change my settings to promote their profit. Seems Mr. D thinks the drivers are your slaves !
