One of my pet peeves (is that a term that dates me?) is asking for hot tea at a restaurant and being served it lukewarm. This might be due to several reasons:
*The water is only lukewarm when it comes to my table. Either it was only warm to start with, not piping hot, or sat in the tea pot too long.
*Perhaps the pot was cold, so the hot water cooled.
*Then the waitress might bring a pot of very hot water to the table, but present me with a cold cup. Sometimes it seems the cup has come from the refrigerator. I sit there with the cup in my hands, trying to warm it slightly, so the water won't get cold as soon as I pour it.
I like my cup of tea to start out hot. Then if it cools, it's my choice.
