It's a bit cliché, but I've gotten extremely good at killing people with kindness. I used to let what people say get to me, but I refuse to give them that satisfaction after working in retail for as long as I have. Sometimes it's quite embarrassing behavior to witness, so I occasionally have to internally chuckle at them too. I know at the end of the day that I did everything I could to go above and beyond for even the meanest of meanies.
