Tipping and Charity Donations

[muddy]

Tipping used to be a reward for good service .
Now it's seems to be added anyway to your bill if you eat out at the most ordinary of restaurants .
And if you pay by card you have the card machine in front of you held by the waiter / waitress asking if you want to add the tip .
I don't like this we will be like America where everyone puts their hand out for a tip no matter how churlish the service .
Now is another thing charity donations .
You are asked at the till if you want to give so much to a " charity " 
I beleive in charity giving and I donate via direct debit to several charities of my choice .
All of which are for children and animals .
So I don't feel any guilt in refusing to be  put on the spot at the till .
Thoughts ?

Quite simple I refuse unless it is coppers to round up. Like putting change in the charity box.
