Aw!!! Thanks so much Harry. It's a story I live with and had not thought of sharing until I read yours this morning.

Like you, I do listen to instructions. They do change.

As for thanking the attendants, always, always. When I was a teacher and going on student outings I'd remind my kids to thank the driver, or zoo keeper, or whoever. Bad manners give me the irrates.

Thanks again Harry, You have made my day.
