It seems like the number of people on the receiving end of a smile is decreasing all the time. Those in the travel industry, food industry, or customer service business get the brunt of grimaces and unsatisfied declarations.
Yes, there are many companies worthy of contempt. Their lack of care or helpfulness, overall lackadaisical attitude towards your issue at hand; many large businesses seem to have lost their bedside manner.
But representing those businesses are actual people. Flesh-and-blood, real life, feeling, breathing, humans. I bet a large percentage of the faces they see every day are not adorned with a welcoming expression. You can either add to the pile of grimaces, or give a free gift. Give one of the few things that cost us nothing: smile.
