I have seen some embarrassments while on field service. One elder loved to stop people in a passage way connecting bus terminal. He often did it that way that he will stop in front of them and prevented people to walk by. However, he caused one elderly woman with a cane to miss her bus. She came back waving the cane over her head screaming that because of him, she missed her bus. We very quickly disappeared in near by apartment complex.
Other time, we were doing field service in Carpathian mountains when we were invited into the farm house. The old man had hand carved huge, old, dinning table with field and forest life motifs: wolves, sheep, goats, bears, but the elder wife refused to sit by the table because she considered the motifs demonic.
