Personal Stress Relief from Economic, Environmental Issues

Correct me if I’m wrong, but I thought people go to blood banks for the benefit of others. I guess, however, in every situation there will be people that find a way to benefit themselves.
On a recent trip to the blood bank, my dad was sitting and waiting his turn. There was a short wait, but one worth waiting for. For those of you who don’t know, generally there are some kind of sweets, in the case cookies, coffee and orange juice, left for those who give blood to help combat lightheadedness and weakness.
As my dad was sitting a couple pulled into the parking lot in a Cadillac Escalade. The couple walked in, went over to where the “sweets” were and loaded their pockets. They then proceeded to go over to the desk to inquire about an appointment. When told that there was a wait, they left. According to my dad, not ten minutes later a man walked in and also proceeded to the snack table, filling his pockets. He too went over to the desk, inquired and left. My dad couldn’t believe the selfishness of these people and wondered how many people actually do this throughout the day.
At that point, my dad went over to get a cup of coffee. He left a dollar on the table. A little while later, the receptionist walked over to the table and inquired as to who left the dollar there. Reluctantly, because he did not do it for recognition, my father answered that he did. The receptionist was so appreciative and expressed the fact that no one ever does that and how thoughtful that was. It’s amazing how so little can mean so much!!!
