I did this the other day. Was out with our 4-H group pulling weeds around some trees that were planted near the animal shelter. well afterwards we all wanted something hot to drink because it had started raining. When we were walking into the local coffee shop an older gentleman I have known for around 5 years was leaving. He held the door open for all us to go through and one of the leaders joked with him about being a door man. He smiled and jokingly said he would accept any tip we were willing to give him. Now I couldn't past that up. I threw my arms around him and gave him a great big hug and a kiss on the cheek. He said he would carry that with him all day long. I think I embarrassed the girls in our group, but this gentleman is always great to talk to and full of good advice when you need it.
