I work in retail, and I can tell you I go beyond the requirement of my job to try and help people. For example, an elderly woman came in the other day and plopped 3 quarts of oil on the counter. As I was ringing it up I noticed that they were all different kinds, so I pointed this out and asked which kind she needed. After doing this back and forth 3 times (I was too busy running the register to help her) she finally got them all right. I asked if somebody else was doing it for her, and offered to do it for free if she came back to the parking lot the next day an hour before I had to work. This isn't some story of how I'm the nicest son of a bitch ever, but the look on her face when I offered that was priceless. She looked genuinely dumbfounded that somebody who made just over minimum wage would care that much. The way I see it, if it's in my power, I'll make sure people are happy. Wether it's reciprocated or not, I see no reason not to try and brighten somebody's day. If somebody continuously takes advantage, I'll stop, but so far that hasn't happened enough for me to give up on trying to be a good person.
