I have not double tipped, but I do take offense at restaurants that put their own gratuity on the bill. That is presumptious and rude, and not restaurants that I would frequent again. Restaurants make a profit just on the food as it is. The person being served should have the call on how much to tip or whether to tip at all, depending on the service.
I agree. In fact, when the tip in included, it is their loss because I always tip extremely generously. More than they tack on. If the tab is inexpensive, I don't tip the usual 20-25% because it would be too little.
I tip people who don't need to be tipped just to see them smile.
And it's not like I am wealthy because I have 0 in my bank account at this time. If I have it, I give it. If I don't, I can't so I don't.
