I am trying to remember -- and I cannot remember ever being invited to a tea at someones' home. Ever.
However, some of the most fancy hotels near us have a regular meal called a "tea". Last time I went, it was $25 per person (plus tax and tip). I was invited to one "tea" which the bride (our relative) gave for the bridal party (and the women in the brides' and grooms' family.) The bride paid. It was very elegant and very wonderful and fancy. I think it was the brides' thank you to her bridal party. She gave them little gifts there too.
