It came as a surprise that the entry teashop is redirected to tearoom. While the latter is an entity for the serving of tea drinks and food, a teashop, or tea shop, is an establishment for the selling of tealeaves. There maybe teashops that serve a pot or a cup of tea, but there are also those that only sell dry leaves or derivative products of tealeaves for making a cup of tea. Many tearooms / teahouses lack the capability to sell tealeaves.

While a teashop maybe a novelty, or antiquity, in some countries, it is common in others. Whoever suggested the redirection should correct this immediately.
