(Our point of sale has crashed, meaning we can not accept cash. My coworker is in the back trying to fix it. Meanwhile, I am in the front handling more customers than I’ve seen my entire shift, while having to turn away those who don’t have cash. A woman walks in and orders a hot chocolate.)

Me: “What size can I get for you?”

Woman: “Just a small.”

Me: “One moment; I will figure out what that will cost.”

(The woman looks around at the other impatient customers, reaches in her wallet and hands me a $10.)

Woman: “It looks like you’ve had a rough night. You can figure it out whenever you get the chance and keep the rest as tip.”

Me: “No, ma’am! Really! That’s too much! It will only take a second!”

Woman: “It’s really okay. Please keep it.”

(That’s more than I normally make in tips in a week. I never saw the woman again.)
