As the holiday shopping season ramps up, malls and stores become more and more crowded which greatly increases the stress levels of many shoppers.  Some of these up tight shoppers vent their increased stress at retail clerks by being rude, mean and nasty toward them.  This, in turn, makes their job incredibly difficult and thankless during what should be a happy of the year.  If you want to make a big difference in these clerks’ lives, you might consider being extra nice to them this time of the year.  As they’re ringing up your merchandise, smile and say something to them that brightens their day.  You’ll find that doing so not only puts a smile on their face, it will put one on yours as well.  Isn’t that what the holiday season is all about?
