The Lovely Marianne and I were visiting daughters in suburban Maryland, which almost always involves a stop at some shopping mall or another. It was lunchtime and I offered to treat the gang to Italian food at a real restaurant just off the food court, so there we were.
When we were done, we all visited in the little rooms to check out the plumbing. I did my business and approached the sink to wash up. I noticed they had a soap pump on the counter, just like the one we have at home, but this one had a small laminated sign taped to its front. Soap pump is finicky, it read. Be very careful.
