So many people want to shame people into tipping more, I can understand it but it comes off as very entitled to me, personally I tip very well usually between 30-50% since I so rarely go out to eat but if you're tipping 10-15% I personally think that's fine and I work as a limousine driver so gratuity is part of my wage, honestly for me getting a fat tip is more of ego boost, I don't care that much about the money.
