This topic comes up on hacker news time and time again, and it is always incredible to see the lengths people go to feel good about not tipping. If you cannot afford to tip, don't. It's not required, and you are probably in a worse place than whoever is receiving your tip. If tipping is a rounding error compared to your compensation, don't tip, since then you're just encouraging tipping, which is expensive for people not you. Remember - by not tipping, you're helping less fortunate consumers. It's the moral choice.
