The saying "no good deed goes unpunished" might seem over the top, but the shoe fits more often than you'd think.
While approaching the world with generosity and kindness is a rewarding lifestyle overall, there are lots of individual moments where doing the "right" thing can wildly backfire. There are a sad amount of people who mistake kindness for weakness, or who don't trust acts of generosity, so the responses to a good deed can truly run the gamut.
I work as a sommelier and waiter at a fine dining restaurant that is popular for romantic dates. Tonight a guy shows up dressed for a date at 7:15 and checks in. He is looks like a quiet, nerdy guy who has obliviously dressed out of his comfort zone for a 1st/2nd/3rd date. After a half hour, he orders a drink. 8:15, still no date.
